The Ups and Downs of Alloy Wheels

Alloy wheels refer to the wheels of your car, motorcycle and truck which are made from an alloy of magnesium or aluminium. Although they are lighter compared to other types of wheels, they provide the same support to your automobile. They also conduct heat better and they generally have enhanced cosmetic appearance than other wheels.

Magnesium alloys are the materials used in the earliest light alloy wheels. The first production of these wheels did not receive a positive feedback from common vehicles owner during the 1960s. However, it was only in the boom of aluminium casting refinement that these wheels were really considered safe since the previous alloy wheels were a bit brittle. Other failures were also observed due to low ductility of magnesium. But when aluminium casting was developed and improved through time, aluminium wheels got their place in the market as low-priced wheels but high performance especially for motorsports.

One interesting fact about alloy wheels is that their purpose does not end with serving as wheels for vehicles alone since they are also used for automobile’s cosmetic purposes. Striking bare-metal finishes can be used on alloys and must be covered with paint or wheel covers.

One downside of alloy wheels is that they are prone to galvanic corrosion. When this occurs, the tires are negatively affected because of the possibility of air leaking from the tires when the owner does not take measures at once. Alloy wheels also pose a difficulty of repair as compared to steel wheels especially when they are bent. Nonetheless, automobile owners with alloy wheels opt for a repair of these wheels since it is more expensive if they are purchased. Aside from this, production of alloy wheels requires greater sums of money compared to the production of standard steel wheels.
