Copper Tungsten Alloy Processed Electrodes With 220HB Hardness
W80Cu20
Tungsten Copper alloy Introduction:
Commonly used copper tungsten alloy contains 10–50 wt.% of copper,
the remaining portion being mostly tungsten. The typical properties
of the alloy depend on its composition. The alloy with less wt.% of
copper has higher density, higher hardness and higher resistivity.
The typical density of CuW90 alloy, with 10% of copper, is 16.75
g/cm3 and 11.85 g/cm3 for CuW50 alloy. CuW90 has higher hardness
and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50.
Tungsten Copper alloy Properties:
Tungsten copper alloy has features, such as, good heat and
electrical conductive, high temperature resistance strength and
ductility.
Tungsten Copper alloy applications:
CuW alloys are used where the combination of high heat resistance,
high electrical and thermal conductivity, and low thermal expansion
are needed. Some of the applications are in electric resistance welding, as electrical contacts, and as heat sinks. As contact material the alloy is resistant to erosion by electric
arc. WCu alloys are also used in electrodes for electrical discharge machining and electrochemical machining.
In addition, tungsten copper alloys are also used as holders,
Pneumatic Cylinders, Resistance Welding Electrodes, Seam Welding
Wheels, Shafts, Shanks, Spot Welding Electrodes, Spot Welding Caps,
Transformers, Welding Arms, Welding controls, Welding Connectors,
Welding Platens, Welding wheels & Blanks.
