CuSn5 C51000 Phosphor Bronze

C51000 (CuSn5) Phosphor Bronze with a nominal composition of 94.80% copper and 5.0% tin, deoxidized with 0.2% phosphorus is the most widely used of the phosphor bronzes, which offering an optimum combinations of such engineering properties as high strength and ductility, superior fatigue and spring characteristics, excellent corrosion resistance, durability for severe service, good bearing qualities with low friction and higher wear resistance, superior forming and spinning, resistance to stress relaxation and good joining properties.
