Tungsten copper alloy electrode is a composite metal material made of high-purity tungsten powder and high-purity, high plasticity and high conductivity copper powder, which is refined by static pressure molding, high-temperature sintering and melting process. Good conductivity, small thermal expansion, no softening at high temperature, high strength, high density, high hardness. It solves the disadvantages of common copper and copper alloy materials such as high electrode consumption and poor machining accuracy
W70 = density (13.8g / cm3), hardness (HRB) ≥ 175, conductivity (ACS) ≥ 42%.
W75 = density (14.5g / cm3), hardness (HRB) ≥ 195, conductivity (ACS) ≥ 38%.
W80 = density (15.15g/cm3), hardness (HRB) ≥ 220, conductivity (ACS) ≥ 34%.
Tungsten copper alloy is an alloy composed of tungsten and copper. The copper content of commonly used alloys is 10% ~ 50%, and the alloys are made by powder metallurgy
The gold method has good electrical and thermal conductivity, good high-temperature strength and certain plasticity. At very high
At temperature, such as above 3000 ℃, copper in the alloy is liquefied and evaporated, which absorbs a large amount of heat and reduces the material surface
Temperature. Such materials are also called metal perspiration materials.
