Product details
Tungsten-copper alloy, also known as cu-tungsten alloy, is composed of copper and refractory tungsten. The copper content of common alloys is 10% ~ 50%.Tungsten-copper alloy has good conductivity, high temperature strength and certain plasticity.At very high temperatures, such as above 3000°C, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the surface temperature of the material, so this kind of material is also known as metal sweating material.
Standard: ASTM B 702
Size: customized
Product characteristics:
-- High strength, high density, high temperature resistance
-- Arc ablative resistance and good electric conductivity
