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 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 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.
Overlay Plated Copper-Lead Bearings for Heavy Duty Service:
.The Copper-Lead Bearings when plated have higher load carrying capacity
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.
