What is the material of copper sleeve
Copper alloy is a kind of alloy material made of hard compound of refractory metal and binding metal through powder metallurgy process.

Hard alloy has high hardness, good wear resistance, strength and toughness, heat resistance, corrosion resistant oil-free bearing corrosion and a series of excellent properties, especially its high hardness and wear resistance, that is, self-lubricating bearing at 500℃ temperature also basically remain unchanged, at 1000℃ still has a very high hardness.

Hard alloy is widely used as cutting tool material, such as turning tool, milling tool, planer tool, drill bit, boring tool, etc., used for cutting cast iron, non-ferrous copper sleeve metal, plastic, chemical fiber, graphite, glass, stone and ordinary steel, but also can be used for cutting heat resistant steel, stainless steel, high manganese steel, tool steel and other difficult to process materials.

Tin Bronze CuSn12 is a bronze for casting.

The specified properties are suitable for the original state (no hardening or processing). 

It has a fairly high base cost among cast bronzes. In addition, it has a fairly high embodied energy and a fairly low ductility.


 Round : 10mm-303mm
 Hollow : 26X14mm - 292X238mm
 Hexagonal : Up to 76mm
 Square : Up to 153mm
 Rectangle : Up to 303mm W
 Bar Length : 3000mm


Good strength combined with the best wear resistance and slip properties. Alloy recommended when dimensional accuracy is required under heavy shock loads.
Will not adapt to edge loading and leaded bronzes. Good resistance to salt water and chemical corrosion. It is recommended that the coupling material be hardened.

Graphite Plugged Tin Bronze Bearing CuSn12 Material


CuSn12 bronze bush must have adequate lubrication and good alignment.



The bronze alloy bearings with graphite plugs provide both good wear resistance and excellent self-lubricating function of this bearing.
This designation allows the bearings to be operated without oiling or lubrication maintenance.
It is widely used in the field of high load and intermittent motion as well as oscillating motion condition.



Tin bronze bushing with added graphite CuSn12 is widely applied in car assembly lines, water turbines, dampers, plastic injection machines, etc. 



● Cylindrical oiles bushing, flanged oilless bush, thrust washer and slide plate are standard fabrication.

● Special designed solid metal bearing and material can be made according to your design.

● Other material can be made based on your requirement.
