In terms of functional characteristics, it is mainly responsible for connecting the wheels with the vehicle body and working with other suspension components to maintain the correct positioning of the wheels. Through precise design, the Upper Control Arm is able to effectively control the up-and-down movement and side-to-side oscillation of the wheels during the vehicle's driving process, ensuring the stability and maneuverability of the vehicle.
It enhances the steering precision of the vehicle, making it easier for the driver to maneuver the vehicle. Its high-strength structural design ensures long-term reliability.
Common alloy grades include steel alloys such as SAE 4130 and SAE 4140, which have excellent strength and toughness; aluminum alloys such as 6061 and 7075, which are lighter in weight and corrosion-resistant; and ductile cast irons such as QT450-10 and QT500-7, which have high strength and abrasion resistance. Different alloy materials can meet the needs of different car models, providing a strong guarantee for the performance of the car.
