UNS C50715 low-tin iron-containing phosphor bronze CuSn2Fe-P, electrical conductivity reach 30~35 %IACS, far higher than conventional C51100 and C51900 phosphor bronze
Trace iron element optimizes matrix structure, improves tensile strength and anti-stress relaxation property, maintains stable contact force under continuous electrification and heating conditions
Excellent bending performance, suitable for ultra-thin material high-speed stamping and complex small-radius bending; stable tin soldering and electroplating characteristics
Moderate wear resistance and good atmospheric corrosion resistance, non-magnetic; ideal material for automotive signal and power elastic contact components
Balanced conductivity, strength and formability; preferred choice for vehicle connectors when requiring low temperature rise and reliable long-term contact performance
