The front upper control arm is a key component in a vehicle's suspension system. It connects the chassis and the steering knuckle, providing stability and control during driving. It is made of high-quality alloy materials, specifically steel alloys with specific compositions to ensure strength, durability, and resistance to fatigue. Common alloy grades include 6060, 6061, 6066, 6082 and other 6-series aluminum alloys. Some aluminum alloy materials of 2-series (such as 2014), 4-series (such as 4032), 5-series (such as 5754) and 7-series (such as 7075) are also used.
