The Copper-Lead Bearings when plated have higher load carrying capacit than straight copper-lead alloys. These overlays are very soft and have excellent embeddability, conformability and corrosion resistance without impairing higher fatigue strength of inner copper-lead-tin alloy.

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 2-3microns thick - preventing the tin.

Copper Powder Metallurgy for Bearings:

.Copper readily forms a protective oxide film when heated in air.

.Copper readily forms a protective sulphide film with oils containing only tracesof 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 steel.

.The protective Organo-tin films formed with oils have a highdesorption temperature

.Hence the copper-tin bronzes result in better bearings than thecopper-zinc brasses.

.Copper alloys usually have a face-centered-cubic structure while themating 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.


Overlay Plated Copper-Lead Bearings for Heavy Duty Service:

.The Copper-Lead Bearings when plated have higher load carrying capacitythan straight copper-lead alloys.

.These overlays are very soft and have excellent embeddability, conformability and corrosion resistance without impairing higher fatiguestrength of inner copper-lead-tin alloy.
