Phosphor Bronze
Phosphor Bronze is a copper-based alloy that includes tin and phosphorus, known for its excellent mechanical properties, corrosion resistance, and fatigue strength. This alloy is widely used in the manufacturing of springs, connectors, bearings, and bushings due to its high strength, durability, and good wear resistance. At Sayverse, we offer premium grades of Phosphor Bronze, including C51900 (CuSn6) and C52100 (CuSn8), each designed for various industrial applications requiring long-lasting performance under mechanical stress.
