Copper alloys are used to make many types of bearings
that require a specific combination of properties.
Copper alloys used for bearings usually have a distributed hard phase
that makes a good lubricant, and are set in a matrix of softer material
that supports it and conducts heat from the bearing surface.
Hard alloys, such as phosphor bronze and aluminum bronze, are used
against hardened steel shafts.
Softer materials, such as leaded bronzes, are used when the shafts
are conventional low alloy steel. |
