Automobile Lightweight Aluminum Alloy Forging

The lightweight of the car is to reduce the overall quality of the car as much as possible under the premise of ensuring the strength and safety performance of the car, so as to improve the power of the car, reduce fuel consumption and reduce emissions. At present, in the lightweight technology of automobiles, light metal materials such as aluminum alloys and magnesium alloys, plastics, aluminum-based composite materials, and titanium alloys are all used. Among metal materials, aluminum alloy has been widely used in automobile hubs, engines, brackets, shells and other parts due to its economical material and easy processing and forming; while aluminum alloy forging is further improved and has high strength. Under certain conditions, the weight can be reduced; the rim, cantilever, steering, and braking system have been applied with forged aluminum alloy parts.

There are 7 advantages of aluminum alloy forging:

1. Light weight; 2. Good strength; 3. Excellent processing performance; 4. Beautiful appearance; 5. Recyclable and less harmful to the environment; 6. Good thermal conductivity and electrical conductivity; 7. Good corrosion resistance.

Typical application of aluminum alloy forging in auto parts

• 1. Forged aluminum alloy wheels: Wheels produced by forging technology have high mechanical strength, light weight, and good heat dissipation, which are of great help to fuel consumption and tire damage.

• 2. Engine pistons: The forged pistons launched by Wiseco in the United States are widely praised for improving engine power. Lightweight forging materials are used in automobile competitions and motorcycle competitions with excellent performance.

• 3. Other application directions: gearboxes, gearboxes, bearing housings, etc.

• 4. Suspension system control arm: A large number of forged aluminum alloy parts have been used in the suspension system of high-end cars such as BMW and Mercedes-Benz, including control arm rods, beams, steering knuckles, claws, etc. Due to the excellent performance and light weight of aluminum alloy, it has been partially adopted in mid-level cars, and there is a trend of further development. For example, in Passat cars, 6 tie rods are used on the front axle.
