Product details
Phosphor bronze
Phosphor bronze alias: tin phosphor bronze: higher corrosion resistance, wear resistance, impact does not produce sparks.Used for medium and heavy load bearing, the highest working temperature 250 ℃.With automatic centering, not sensitive to deflection, bearing uniform bearing capacity, can be subjected to radial load at the same time, self-lubrication without maintenance and other characteristics.Tin phosphor bronze is an alloy of copper, has good electrical conductivity, not easy to heat, ensure safety and has a strong fatigue resistance.Tin phosphor bronze socket spring hardwired electrical structure, no rivets or friction contacts, can ensure good contact, good elasticity, smooth dial-insert.The alloy has excellent machining properties and chip forming properties, which can quickly shorten the processing time of parts.Phosphor copper, as an intermediate alloy, is widely used in copper casting, solder and other fields and plays an important role in the development of national economy.

C5191 features and USES:
It has high phosphorous content, high fatigue strength, good elasticity and wear resistance, but it can only be processed under cold pressure due to its hot brittleness.In addition to being used as springs and wear-resistant parts, it is mainly used in paper industry to make wear-resistant copper mesh and parts under the condition of unit load < 981Mpa and circumference speed < 3m/s.
