High Flow Shock Base Valve for Hydraulic Suspension Systems

65 HB Fe-C-Cu material foot valve with crushing strength ≥ 7KN used in car shock

This high-flow shock absorber base valve (foot valve) is precision-engineered from Fe-C-Cu powder metallurgy material, delivering exceptional crushing strength exceeding 7KN. Designed specifically for automotive hydraulic suspension systems, it regulates oil flow between the reservoir and compression chamber to ensure consistent damping performance under demanding driving conditions. Manufactured by XIAYI with over 20 years of powder metallurgy expertise, this component meets IATF 16949:2016 automotive quality standards.

Every base valve undergoes XIAYI's rigorous 8-step powder metallurgy process with inline inspection at each critical stage to ensure consistent quality and dimensional accuracy:

• High density: 6.75-7.1 g/cm³ for superior mechanical strength and wear resistance
• Hardness: HRB 70-85, meeting demanding automotive durability requirements
• Carbonitriding quenching available for enhanced surface hardness and fatigue life
• Rupture test: 13110N, demonstrating exceptional structural integrity under extreme loads
• High precision manufacturing with tight dimensional tolerances
• IATF 16949:2016 certified (formerly ISO/TS 16949), the global automotive quality management standard
• Consistent oil flow control for stable shock absorber damping performance
• Self-lubricating properties from controlled porosity in powder metallurgy structure

XIA YI produces different kinds of powder metal parts. They can be used in different area such in automobile, motorcycle and different industries.
