The Acid Test
At the top of our list, we have the good old acid test. Because alloy wheels are made from an alloy of aluminum and another metal, when acid is poured on them, there won’t be corrosion. However, if corrosion does occur then that wheel isn’t made of aluminum.
What material are wheels made of?

Aluminum wheels provide a lighter mass weight for sports cars, and are also machined for a brilliant appearance.
Are aluminum wheels stronger than steel?
Probably the most surprising benefit of aluminum wheels is that because they are actually an alloy metal, they are stronger than traditional steel wheels. This means that, in addition to being lighter, you can also carry heavier loads.
Steel wheels are hefty and can withstand a lot of punishment, but they strain the axle and reduce the vehicle’s fuel economy. Steel wheels are used on police vehicles because they can smash into curbs repeatedly without breaking.

Which is stronger aluminium or chrome?
Both chrome and polished aluminum finish have their share of ups and downs. Chrome finish is more-tougher and easier to maintain, while polished aluminum looks more natural and is lighter overall.
Why do chrome wheels peel?
Chrome peel is a condition in which the chrome coating of a wheel, usually that of a car, disintegrates in the area where the tire is bound to the wheel. Gradually the air escapes and a slow leak of pressure from the tire occurs.
When appropriately maintained, chrome wheels will last many years because they have one of the strongest wheel coatings. The electroplating procedure makes chrome wheels highly resilient and tolerant to corrosion, in addition to rendering a polished finish. But this sturdiness depends on regular maintenance.
