1. Ultra-strong chromium-molybdenum alloy construction exceeds OEM tensile strength by 22%, engineered specifically for Mercedes' dynamic load requirements.
2. Every batch undergoes full material traceability audits (ISO 9001:2015) and 23-point quality checks documented through blockchain-verified production logs.
3. Surface treatment: The control arm needs surface treatment in the production process, such as spraying, zinc plating, anodizing, etc., to improve the corrosion resistance and aesthetics of the control arm.
