A car's brakes are among its most important components. Brakes are essential for maintaining your car's overall performance and safety. Disc brakes, which are among the most common brake types in cars, come in a variety of materials. Brakes with aluminium discs offer several distinct advantages.
One of the key advantages of aluminium brake discs is durability. Aluminium is strong and resists corrosion and rusting, even over extended periods of time. After long periods of use, aluminium brake discs can be machined to restore a smooth surface, allowing them to be used for longer than brake discs made from other materials.
Another major advantage of aluminium brake discs is that they are light. According to Michigan Tech's Institute of Materials Processing, a car equipped with aluminium discs can weigh up to 11.3kg. less than a car that has traditional steel discs. This reduced weight can lead to better performance, faster acceleration, and shorter stopping distance. Less weight also means better fuel economy---aluminium brake discs can save drivers between three and eight gallons of gas a year.
Aluminium discs are also less costly to transport and ship because they weigh less, saving manufacturers and retailers money over conventional, heavier brake discs.
Aluminium brake discs dissipate heat better than steel discs do. This prevents too much heat from building up on the surface of the disc, where it can damage the brake pads or prevent the brakes from working properly. Heat dissipation is important to overall vehicle safety, as well as to the durability of the entire braking system.
