Alloy Wheel

Alloy wheel Alloy wheels are wheels that are made from an alloy of aluminium or magnesium. Alloys are

mixtures of a metal and other elements. They generally provide greater strength over pure metals, which are usually much softer and more ductile. Alloys of aluminium or magnesium are typically lighter for the same strength, provide better heat conduction, and often produce improved cosmetic appearance over steel wheels. Although steel, the most common m aterial used in wheel production, is an alloy of iron and carbon, the term "alloy wheel" is usually reserved for wheels made from nonferrous alloys. Casting

The casting process for a Rays Wheel consists of four steps: 

Fusion – Aluminum metal is heated up into molten liquid.



Molten Metal Treating  – Process of removing impurities from f rom molten aluminum. Molten aluminum with no impurities are moved into a holding furnace.



Casting – Molten aluminum is poured into a die to form the wheel.



Machine Work – Various chemicals are used to prevent corrosion and protect the surface of the wheel

The major casting processes for wheels are: 

Low-pressure die casting (mainly)



Gravity permanent mould casting (less used)



Squeeze-casting process (marginally used)

Rarely used are the following processes: 

Counter pressure die casting



Casting-forging (Cobapress)



Thixocasting

Materials

The alloys employed have to meet a range of sometimes conflicting requirements: 

Good metal-mould casting properties (castability, susceptibility to hot tearing and shrinkage characteristics)



Ability to withstand physical impact (elongation and impact strength)



Corrosion resistance (normal and saline atmospheres)



Fatigue resistance

These requirements have led to the widespread use of hypoeutectic Al-Si primary alloys with 7 to 12% silicon content, varying contents of magnesium (strength-elongation compromise), low iron and minor impurity concentrations.

Advantages

Alloy wheels decrease the unsprung weight, and because of this lower weight, there is an improvement in the car's handling, particularly in steering precision. A lighter wheel also makes it easier for the car to accelerate, and this can give drivers a small increase in gas mileage. Are alloy wheels better than steel? Alloy wheels are made of an alloy  of light metals, namely aluminium, nickel, magnesium, or a

combination of these metals. They of fer performance advantages over steel wheels, as they are often several pounds lighter per wheel - less weight means quicker acceleration and faster stopping.
