W80Cu20 Alloy Electrode

W80Cu20 alloy electrodes are metal-based composite materials composed of approximately 80% tungsten (W) and approximately 20% copper (Cu), often referred to as tungsten-copper alloy CuW80 or CUW80. They combine the high melting point, high hardness, and high density of tungsten with the high electrical and thermal conductivity of copper, forming a pseudo-alloy with complementary properties. Their standard chemical composition ranges from 79% to 81% tungsten (W) to 19% to 21% copper (Cu), with total impurities controlled at extremely low levels. W80Cu20 alloy electrodes have broken through the bottleneck of the incompatibility between high temperature resistance and high electrical conductivity, playing an irreplaceable role in high-end and general industrial fields such as power, electronics, aerospace, and machinery manufacturing.
