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 copper alloys against iron alloys.
Copper readily forms a protective oxide film when heated in air, Copper readily forms a protective sulphide film with oils containing only traces of sulphur compounds, Copper has a high thermal conductivity for the dissipation of the frictional heat, thus reducing the surface temperature, Tin strengthens copper and hardens it sufficiently to be compatiblewith unhardened stee, 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 copper alloys against iron alloys.
The steel backing to give the bearing strength and regidity, The copper-lead-tin intermediate, alloy linin is permanently bonded to the steel back by intering process. It is the lining alloy that will stand up under extreme bearing loads.A nickel plate or nickel barrier - just 2-3 microns thick - preventing the tin.
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.
The lead-tin-copper plate that easily confirms to slight irregularitie in the crankshaft journals during engine run-in, The pure tin flash plate which provides corrosion and rust resistance all over.
