The Rear Knuckle plays a vital role in the automobile. As a key component connecting the wheels to the suspension system, it can precisely control the movement of the wheels to ensure the stability and safety of the vehicle.
In terms of applications, the metal spares are widely used in the automotive industry. Whether in passenger cars, commercial vehicles or off-road vehicles, Rear Knuckle is one of the core components to ensure the handling performance of vehicles. Meanwhile, in racing and high-performance vehicles, its precise control performance has been maximized.
Regarding alloy grades, the common ones are steel alloys such as SAE 4130 and SAE 4140, which have high strength and good toughness, and can withstand all kinds of stresses in vehicle driving. Aluminum alloys such as 6061 and 7075 are also used, which are lighter in weight while providing some strength and corrosion resistance. In addition, there are ductile cast irons such as QT450-10 and QT500-7, which offer high strength and wear resistance. The choice of these alloys depends on the needs and performance requirements of the different vehicles.
