Phosphor bronze has higher corrosion resistance, abrasion resistance, and no sparks during impact. Used for medium-speed and heavy-duty bearings, with a maximum working temperature of 250℃. It has the characteristics of automatic centering, insensitive to deflection, uniform bearing force, high bearing capacity, radial load at the same time, and self-lubricating without maintenance. Tin phosphor bronze is a kind of copper alloy, which has good electrical conductivity, is not easy to generate heat, ensures safety and has strong fatigue resistance. The socket reed of tin-phosphorus bronze has a hard-wired electrical structure, no rivet connection or frictionless contact, which can ensure good contact, good elasticity, and smooth insertion. The alloy has excellent machining properties and chip-forming properties, which can quickly shorten the processing time of parts.
