Phosphor Bronze Alloy is an alloy of copper, tin, and phosphorus. It is hard and can be used to make springs. Use P to remove oxygen from pure copper and bronze (Cu-Sn) and leave a small amount of P, and add 1% P to Cu alloy to improve mechanical properties (toughness, elasticity, wear resistance, corrosion resistance). Mainly used as wear-resistant parts and elastic elements. Computer connectors, mobile phone connectors, high-tech industry connectors, electronic and electrical springs, switches, electronic product slots, buttons, electrical connectors, lead frames, vibrators and terminals, etc.
A bronze with tin and phosphorus as the main alloying elements. Contains 2-8% tin, 0.1-0.4% phosphorus, and the rest is copper. It is mainly used as wear-resistant parts and elastic elements in industry. Plates and strips are used for springs, switches, lead frames, connectors, vibrators, bellows, fuse clips, bushings, etc. for electronic and electrical devices, especially for springs that require high-performance elasticity. Castings are used for gears, worm gears, bearings, bushings, sleeves, blades, and other general mechanical parts.
