Tin strengthens copper and hardens it sufficiently to be compatible with unhardened steel. The protective Organo-tin films formed with oils have a high desorption temperature. Hence the copper-tin bronzes result in better bearings than the copper-zinc brasses. Copper alloys usually have a face-centered-cubic structure while the mating surface is usually a ferrous alloy with a body-centered-cubic structure. This difference contributes to the anti-seizure characteristics of copperalloys against iron alloys.
Lowers Lub. Oil Consumption, Maintains specified fuel Consumption for longer service, Can be used against hardened as well as unhardened shaft, Protects shaft from extensive damage, Embeds dust and debris carried by the Lubricant and prevents scoring at high loads.
