Description
Phosphor bronze is an alloy of copper, tin, and phosphorus. It is hard and can be used to make springs [1]. 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.
Performance:
Phosphor bronze has higher corrosion resistance, wear resistance, and does not spark when impacted. For medium-speed, heavy-duty bearings, the maximum working temperature is 250°C. It has the characteristics of self-aligning, insensitive to deflection, uniform bearing force and high bearing capacity, can bear radial load at the same time, self-lubricating and maintenance-free. Tin phosphor bronze is a kind of alloy copper, which has good electrical conductivity, is not easy to generate heat, ensures safety and has strong fatigue resistance. Tin phosphor bronze socket reed hard-wired electrical structure, no rivet connection or no friction contact, can ensure good contact, good elasticity, and smooth insertion and insertion. The alloy has excellent machining performance and chip forming performance, which can quickly shorten the processing time of parts, etc.
