Copper alloy with Cu-Sn-P as the main alloying element is called tin-phosphor bronze strip. As a pioneer of phosphor bronze strip suppliers, we offer the tin phosphor bronze tape products in good quality, which can be used in CPU sockets, mobile phone keys, car terminals, connectors, electronic connectors, electronic connectors, bellows, spring plates, harmonica friction plates, wear-resistant parts of instruments, and Antimagnetic parts, automotive parts, electrical parts of machinery.
Good yield strength and fatigue strength
Good elastic properties
Excellent processing performance and bending performance
Better ductility, durability, corrosion resistance
