1)Description of Copper Bushing

Copper bushing is a tubular part made of copper alloy as raw material, common copper alloys are tin bronze,

aluminum bronze, lead bronze, etc., through casting or machining molding, used to reduce the friction between mechanical parts.

2)Feature and Advantage of Copper Bushing

a) Good wear resistance: copper alloy itself has moderate hardness and self-lubrication,

which can maintain stable dimensional accuracy in long-term use.
b) Strong thermal conductivity: the heat generated by friction can be quickly dispersed to

avoid local overheating and prolong service life.
c) Good chemical stability: it is not easy to rust and be corroded in many complex environments,

and has a wide range of applications.

3)Application of Copper Bushing

Commonly used in automobile engines, machine tool spindles and other mechanical components

that require friction reduction and wear resistance.
