The load-carrying capacity of tin bronze is higher than that of lead bronze because the strength of tin bronze is higher than that of lead bronze. Hebei tin bronze is mainly composed of copper, tin, zinc, and lead. The main ones are CUSN5ZN5PB5, CUSN8, and CUSN6. According to experience, its strength and hardness are a bit higher than that of lead bronze. Lead bronze is mainly composed of three elements: copper, lead and tin. It has good machinability and lubricity. The higher the lead content, the better the lubricity and the lower the bearing capacity.
Common lead bronzes are CUSN8PB15 and CUSN4PB20, so the carrying capacity of tin bronze is higher than that of lead bronze. Bronze is the old name of copper-tin alloy, now called tin bronze, which is an alloy composed of phosphor and copper, called phosphor bronze. The difference is that phosphor bronze has high hardness and wear resistance. Ancient bronzes are mostly phosphor bronze. Tin phosphor bronze has higher corrosion resistance and abrasion resistance. It does not spark when punching out. It is used for medium speed and heavy load with bearings and works. The maximum temperature is 250°C.
It has the characteristics of self-aligning that is not sensitive to deflection, the bearing is uniformly loaded, the bearing capacity is high, and it can be subjected to radial loads at the same time, and it is self-lubricating and requires no 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 during the processing of parts.
