Where Did Alloy Wheels Come from?

Nowadays we take the availability of alloy wheels for granted, but they have in fact only been popular, and widely available, since the 1980s. So where did they come from?

alloy-wheel-finished-fbAlloy wheels have been offered sporadically since 1924. Before this, wheels were usually comprised of two pieces of pressed steel – the rim and the disc – which were welded together.  The other option was an aluminium rim, which was connected to the centre by metal spokes.

One of the first to realise that alloy wheels have the power to offer greater stiffness and reduced weight was Ettore Bugatti, who featured them on his Type 35 in 1924. The wheels also improved brake cooling, and Bugatti continued to develop cast alloy wheels until he arrived at the stunning 24 inch version used on the Type 41 Royale.

After the Second World War, the alloy designs were augmented by Panhard, which developed a radially finned aluminium brake drum to double as the wheel centre. Cadillac and Pontiac later introduced similar versions, which also had a centre cap covering the mounting lugs. Many vehicles had an adapted plate that allowed for the open-centre rims to work with wheel balancing machines.

diamond-alloys-corrosion-refurbishment-triumphThe 60s saw more makes offering alloys, although they still weren’t hugely popular. Abarth put magnesium wheels on most of their models from 1962, while Ferrari introduced their first alloy, the magnesium Cromodora Starburst, on their 275 GTB in 1964. The Corvette, the Alfa Romeo GTA, the 1965 Mustang, the 1965 Lamborghini Miura and the 1966 Fiat Dino also featured alloy wheels. Porsche came to the party slightly later, adding their first alloy to the Porsche 911S in 1966. They were consistent, however, and the alloy has remained standard on the 911 for decades. Aston Martin came to the party with an alloy on the DBS V8 in 1969, with Mercedes following a year later.

A variety of different wheels were favoured by different manufacturers, but it’s estimated that the Minilight wheel, introduced in 1964, was the most popular aftermarket wheel ever. Available in both magnesium and aluminium, the wheels were used by factory competition teams everywhere. The first budget-friendly wheel available to all motorists was an aluminium alloy offered on the VW Golf, Scirroco, Passat and Audi in 1974.

Alloy wheels finally reached peak popularity in the 1980s, and have remained that way ever since. Although their styling and design has evolved over the years, the benefits remain: better stiffness, lighter weight and unique styling that puts your own individual stamp on your car.

Why Powder Coat Alloy Wheels?

steveHave you ever wondered why alloy wheel specialists recommends a powder coat process for repairing and refurbishing alloy wheels?

Diamond Alloys is a powder coat specialist and to help you answer this question we have put together a list of the benefits of applying a powder coat process to your alloys along with some common questions with their answers.

The Benefits of Powder Coating Alloy Wheels

  • You’ll achieve a better and more durable finish with a powder coat.
  • Achieves a longer lasting result compared to painting alone.
  • Typically a one coat finish it can offer a quicker turnaround for completion.
  • Powder coating is an environmentally safe process because it produces few volatile organic compounds (or VOCs).
  • Creates the most even finished surface (horizontal and vertical) because the powder is sprayed and heated without drips or application traces.

Most Commonly asked Question About Powder Coating?

diamond-alloys-powder-coat

What colour finish can I achieve with a powder coat?
There is a wide range of colours available. You can also add texture, achieve a matt or gloss finish.

Is a powder coat finish dangerous?
Powder coating are not classified as dangerous and there are no solvents used in powder coating.

Does powder coating prevent rust?
Unfortunately no, but the finish is durable and last longer than many other processes which is why it is so possible, ensuring return visits to the workshop are fewer.

Can I get powder coated alloys diamond cut?
Yes, all our Diamond Cut allows wheels have a powder coat base. This can be painted a colour to accentuate the effect of the cut.

Can I get a smart repair powder coat?
No. Powder coatings are a workshop applied using specialised equipment. The equipment includes an electrostatic spray gun, spray booth and an oven to bake the coating. On site application is not possible given the hot curing cycle required to fuse the coating.


What has static electricity got to do with powder coating?
Powder coatings are electrostatically charged by the spray gun. This works by very high voltage (80,000 to 100,000 volts) being delivered to the electrode. This high voltage ionizes the air creating a field of electrons or negative charge. The powder is pneumatically conveyed into this electrostatic field, picks up a charge then heads to the nearest ground. So lots of static electricity is generated by the spray system.

diamond-alloys-powder-coat2How should I care for my powder coated alloys?
Pollution, dirt, grime and salt can all accumulate on a powder coated surface over time. To extend the life of your powder coated alloy wheels a simple regular maintenance program should be implemented for the removal of residues.

In areas where pollutants are more likely, especially in coastal or industrial regions, a cleaning program should be carried out on a more frequent basis. To clean a powder coated surface, carefully remove any loose deposits with a wet sponge and then use a soft non-abrasive brush or cloth in combination with a mild household detergent solution to remove dust, salt and other residues. Finally rinse all powder coated surfaces with clean water.

Get the must have alloy wheel look for 2017

_bs_8418According to Oliver Rak, Project Manager at Mercedes Benz, when it comes to what is on trend for alloy wheels this year “It is a continuation of last year’s trends: large formats are still very much ‘in’, as well as are light-alloy wheels with a high-sheen finish, whose allure stems from the contrast between the seemingly bare metal surface and the painted areas.”

This seems in line with trends at Diamond Alloys alloy wheel repair and refurbishment centre in West London. General manager Amerjit Ubhi commented, “Although we do get requests for Shadow Chrome or Gloss black finish, by far the most popular request we have for an alloy wheel finish is a Diamond Cut. The process starts with a thorough strip down and then powder coat which gives the alloy wheel colour. Then the face of the wheel is cut to reveal a shiny metal finish (a bit like a CD); if a dark colour base is chosen the Diamond Cut will really accentuate the design of the rim. The alloy wheel is then lacquered to protect the finish.  It’s a great look and I’m not surprised it’s the height of fashion for rims!”

Take a look at some Diamond Cut alloy wheel repairs we have carried out in our London wheel repair workshop.

A Cut Above the Rest – Diamond Cutting Alloy Wheels

img_5661-2We love to shout about how good we are at repairing and refurbishing alloy wheels. We believe the proof is in the pudding and so regularly share finished wheels on our news page and social media so you can see just how good our Diamond Cutting finish is.

The process cuts a very thin layer of alloy away to remove any kerbing damage and produces a shiny effect a bit like the back of a CD. This can be contrasted against a dark black gloss or shadow chrome finish for dramatic affect to accentuate the shape of the alloys, or with standard silver for a more subtle effect.

Take a look at our galleries and it might inspire you to opt for a new look! Our technicians have years of experience and are highly skilled and can create a finish to your desired look. If you have seen something you like on another car, then snap a picture and show us, we’ll do our best to create a similar look depending on your alloys spoke design.

ALL our alloy wheels have a powder coat base as standard including our Diamond Cut alloy wheels. This gives a sound base which is smooth and long lasting; remember, we powder coat front and back, not just the face of the wheel.

At Diamond Alloys, We’ve Got Your Back

img_6760-smallHave you ever had someone ‘pop in’ to see you unexpectedly? Did you then do what millions of us do, and spend five minutes frantically making the place look as clean and tidy as possible – perhaps by hiding all the dirty dishes in a cupboard? There’s no shame in these temporary measures, because that’s just what they are – temporary. You’re simply trying to give your guest a pleasant experience, not to mention protect your reputation as a homeowner! What you’re not doing is permanently keeping those dirty plates in the cupboard, or leaving that pile of un-ironed laundry hidden behind the sofa forever. That would be terrible, right?

img_0929-3smallIf you agree with that, then you can imagine how we feel about companies that only repair and maintain the front of the wheel. It’s the same kind of thing – they’re only treating the areas that people can see and letting the hidden areas, in this case the back of the alloy, become filthy and unloved. The worst thing is that it often isn’t made clear that this is what the company has done, mean that customers think that their wheels are more protected than they are in reality.

img_3071-2smallHere at Diamond Alloys we powder coat and paint the entire alloy, not just the front. This is because we are committed to providing the highest quality service possible, and because we believe that all parts of an alloy should be cared for equally, regardless of whether or not they are visible. Powder coating the whole alloy results in longer-lasting rims, which is what anyone who cares about the health of their wheels deserves.

If you’d like to find out more about any of our repair processes, from powder coating to diamond cutting, please check out our blogs which document them all in detail. You can even watch our YouTube videos to see exactly how we do the repairs and painting – on both sides of the wheel!

Diamonds are a Car’s Best Friend

range-rover-alloysOnce you start looking into repairs that will preserve the aesthetics of your car’s wheels, it won’t be long before your research leads you to the phrase ‘diamond cut finish’, or ‘diamond cutting’. This is because a diamond cut is widely regarded as the crème de la crème of alloy finishes, one that provides the highest possible quality and precision, giving your wheels a prestigious, high calibre look.

Diamond cutting works by finely cutting the alloy wheel on a lathe, removing only what metal is required – nothing more, nothing less. The process starts, however, with a specialist clean of your wheel, completely removing all dirt, grit and tar, ensuring that our team can make a thorough examination and decide on the best possible repair for the damage.

vw-caddy-van-alloy-wheel-refurbishmentAfter the cleaning the wheel is powder coated, allowing for a smoother finish once the repair is complete. Then comes the precision cutting, which leaves a pure, shiny finish. Following this expert diamond cut comes a coating of scratch-proof lacquer, after which the wheel is baked in the oven and then carefully inspected to ensure it meets our quality standards.

Even if you’re not fanatical about your wheel aesthetics, it’s worth considering a diamond cut repair because many car companies fit diamond cut alloys to their vehicles as standard. If your car is intended to come with this style of alloys then it’s worth preserving the continuity, not just to ensure the car looks its best but also to give yourself the best possible chance of attracting a high resale price should you ever come to put it on the market.

If you have any questions about our diamond cutting repair service, or want to know whether it’s appropriate for your wheels, then please do get in touch.

What colour should your alloy wheels be?

custom-alloy-wheel-paintOne of the questions we get asked a lot is ‘what colour should my alloy wheels be?’ This is often because people see car manufacturers introducing models with particular colours of alloy, particularly for higher end cars, and assume that there is a right way and a wrong way to style their car.

Fortunately, however, the truth is that there is no right answer to the above question – your alloys can be any colour you choose! We think that your car’s wheels should both complement the rest of the car and your own personal aesthetic, but there are no strict rules on how to do this. Although the majority of alloys you see on the road will probably be silver, there are a thousand different colours and styles for you to choose from.

IMG_4708-2Black, for example, is becoming a very popular choice for discerning car owners, especially those with sportier models. (Let’s save the philosophical argument about whether or not black is actually a colour later!) Black goes with a wide variety of body colours, and is also a great base for two-tone diamond cut colours if you want to get really arty!

custom_alloy_wheel_refurbishment (4)If your personality is a bit more flamboyant, how about a bright colour? There’s the whole spectrum to choose from, with metallic sheens like gold and bright sporty colours like orange able to completely transform the look of your car. You can further expand on the almost limitless range of colours by opting for custom effects such as marbling, which can create a truly eye-catching result.

range-rover-alloy-wheelsLet’s not forget silver painted finishes, of course, which can vary from super-bright metallics to flat powerful greys such as gunmetal. Anthracite, a near-black grey with a distinctive sheen, is becoming a go-to choice for many drivers looking to update their look.

Get Ready for Your Winter Wheels Care Regime – Part Three

car-wheels-foamSo you’ve got your tools, you’ve protected your alloys from brake dust – now how do you actually clean them? Follow our step-by-step guide below for foolproof, sparkling results. You can incorporate this as part of your regular car cleaning regime, but we’d advise washing the wheels before the rest of the car – this ensures you don’t have dirt and brake dust splashing over your clean bodywork!

  1. Clean your tyres and wheel wells using specialist tyre cleaner and brushes – this stops you making a mess over your clean alloys later. Remember that your tyre brush should be stiff and should under no circumstances be used on your alloys!
  2. Give your wheels a thorough rinse

This helps to remove brake dust and any loose dirt, saving you work later. Ideally you want to create a hard stream of water so a hose is best, or you can use a plastic water bottle if you’re in a pinch!

  1. wheel-cleanApply the wheel cleaner

Follow the instructions on the cleaner you’ve chosen – they really are there for a reason!

  1. Scrub the wheel with your soft alloy brush

Your soft brush will gently work away all that grime and brake dust, without damaging the surface of your alloy. Remember to keep the alloy wet throughout the process (otherwise you’ll ruin your finish) and work all around the back and front of the wheel to ensure you scrub off all the dirt. Your clean and dirty water buckets will come in very handy here.

  1. jet-washRinse everything thoroughly. There’s no point scrimping at this stage so go to town with your hose or buckets.
  2. Dry your wheels with a towel

For best results you’ll have to dry your wheels manually – it stops water spots appearing and ensures you get the optimum finish. Your towel will accumulate residual brake dust over time so never use this on other parts of your car, unless you like the corroded paint look.

Now you’ve mastered the basic thorough clean of your wheels you’re ready for clay detailing, which can be done straight after this process. Stay tuned for our next blog to find out how to master the art and ensure you remove every last bit of dirt and dust from your wheels.

A Picture Tells a Thousand Words

Ever wondered exactly what happens after you’ve dropped off your alloys for repair? If you don’t have time to look through our previous blogs for details of individual processes, why not watch our quick new video, which provides a step-by-step guide in just a minute and a half?

Commencing at the point where we separate the alloy from the tyre, the video takes you through many of the complex processes we use to make your alloys look as good as new – although our experts do make them look easy!

One of the things many people find particularly fascinating is the alloy oven, in which we bake your wheels to ensure the coating adheres successfully and provides a high quality, smooth and long lasting finish.

Other interesting aspects are sanding, priming, powder coating and re-balancing – although some people have also expressed surprise at the fact that we give every part an ID number, which is essential in ensuring we don’t mix up your wheels!

These new McLaren wheels are very much of this earth

When you think of top hypercar brand McLaren, the pictures that normally form in your mind are of shiny metal, perfect symmetry and huge, roaring engines. It is typical of the brand’s innovative thinking, therefore, that their new wheels are entirely the opposite of this – their design instead taken from the chaotic and unpredictable life found in nature

The keystone of their inspiration for these wheels is tree roots, giving rise to a unique design that’s never before been seen on an automobile. It’s no surprise that they’re looking to nature for their design concepts – after all the most beautiful concepts in art and mathematics are all rooted here (excuse the pun) – but it is symptomatic of the marque’s fearlessness and confidence in their audience.

Whereas ‘normal’ wheels have symmetrical spokes, the McLaren designs will borrow the intricate patterns formed by roots to create new, lightweight and entirely irregular wheels. While we’re yet to see the design, we’re going to go out on a limb (or should that be branch?) and say these may be the most eye-catching wheels ever made.

Those with an engineering mindset will appreciate how difficult it will be to create these wheels, something that’s little concern to perfection-obsessed McLaren but a significant deterrent to anyone looking to copy their designs. Not only will wheels inspired by roots be beautiful, but they also have other surprising benefits – because the spokes will be curvy, there is much less impact on the centre of the wheel when the wheel gets hit. It’s looking like the lightweight, think spokes will be counterbalanced by material behind them, which in turn will add extra strength to the whole design.

The wheels are due to grace the McLaren P1 at some point in the near future – we’ll bring you pictures as soon as we can.
