What conditions should a qualified control arm meet

The car control arm is an important part of the car chassis. Its function is to transmit the power of the engine to the wheels and drive the vehicle. Jiahangaero said that the requirements for the car control arm are therefore very high:

• 1. High strength.

• 2. Light weight.

• 3. Good rigidity.

• 4. Good fatigue resistance.

• 5. Have sufficient toughness.

• 6. Smooth surface.

• 7. High wear resistance.

• 8. Good machinability.

• 9. Good corrosion resistance and heat resistance.

In addition, Jiahangaero said that due to these characteristics of aluminum alloy, it has better mechanical properties than steel. In the same conditions, the use of aluminum alloy can save fuel by 3% to 5% compared to the body made of cast iron. Therefore, from the perspective of energy saving, the use of aluminum alloy body is more cost-effective than the use of steel.
