high density tungsten copper W-Cu alloy block electrode high hardness
The tungsten-copper alloy combines the advantages of tungsten and
copper, in which tungsten has a high melting point (3410 for
tungsten and 1534 for iron) and high density (19.34g/cm3 for
tungsten and 7.8g/cm3 for iron).
Copper has excellent electrical and thermal conductivity,
tungsten-copper alloy (general composition range is WCu10~WCu70)
has uniform microstructure, high temperature resistance, high
strength, arc ablation resistance, high density, moderate
electrical and thermal conductivity.
Widely used in military high temperature resistant materials, high
voltage switch electrical alloy, electrical processing electrode,
microelectronic materials.
As parts and components, they are widely used in aerospace,
electronics, electric power, metallurgy, machinery, sports
equipment and other industries.
Product features
The tungsten-copper alloy electrode is a kind of composite metal
material which is made of the combination of high purity black
powder and high purity and high conductivity copper powder, and is
refined by the process of static pressing, high temperature
sintering and melting.
Good electrical conductivity, small thermal expansion, no softening
at high temperature, high strength, high density, high hardness.
The defects of electroetching of ordinary copper and copper alloy
materials such as high electrode consumption and poor machining
accuracy are solved.
