Product Overview
The Automotive Alloy Steering Knuckle is a critical core component in modern passenger vehicles, SUVs, and high-performance automotive chassis steering systems.
It is manufactured using high-strength lightweight alloys such as aluminum or aluminum-magnesium alloys, significantly reducing unsprung mass while improving vehicle handling performance and fuel efficiency, while maintaining excellent load-bearing capacity and structural strength.
The steering knuckle connects the control arm, tie rod, and wheel hub, serving as a key load-transfer hub for steering, suspension, and wheel load transmission. The use of alloy materials improves strength, corrosion resistance, thermal conductivity, and NVH performance, meeting the lightweight and high-performance requirements of modern ICE and new energy vehicles.
With over 40 years of precision casting and machining experience, Sangroove (Jiangsu) Machinery Co., Ltd. specializes in manufacturing automotive alloy steering knuckles, aluminum chassis components, and suspension connection parts for global OEM and Tier 1 suppliers.
