ALLOY WHEEL


-made from an alloy of aluminium or magnesium.

-They are typically lighter for the same strength and provide better heat conduction and improved cosmetic appearance.

-Lighter wheels can improve handling by reducing unsprung mass, allowing suspension to follow the terrain more closely and thus improve grip

-however not all alloy wheels are lighter than their steel equivalents.

-Reduction in overall vehicle mass can also help to reduce fuel consumption.

-Better heat conduction can help dissipate heat from the brakes, which improves braking performance in more demanding driving conditions and reduces the chance of brake failure due to overheating.

-Alloy wheels are prone to galvanic corrosion if appropriate preventive measures are not taken, which can in turn cause the tires to leak air.

-alloy wheels are more difficult to repair than steel wheels when bent, but their higher price usually makes repairs cheaper than replacement.

-Most alloy wheels are manufactured using casting, but some are forged. Forged wheels are usually lighter, stronger, but much more expensive than cast wheels
