The B5 Control arm plays an important role in automobiles. Firstly, it can precisely control the position and movement of the wheels to enhance the stability of vehicle handling. During driving, it effectively withstands various impacts from the road, ensures the wheels are always at the right angle, and reduces tire wear. Secondly, the B5 Control arm made of high quality materials has a longer service life and reduces maintenance costs.

In terms of aluminum alloy grades, the common ones are 6061 aluminum alloy and 7075 aluminum alloy. 6061 aluminum alloy has good machinability and corrosion resistance, moderate strength, which is suitable for manufacturing the main structure of the B5 Control arm. 7075 aluminum alloy has higher strength and better toughness, which can be used in the key parts to improve the overall performance.
