Tungsten-Nickel-Copper Alloys
Description
Tungsten-Nickel-Copper (W-Ni-Cu) alloy refers to an important group of tungsten-based heavy alloys in which nickel and copper are added to tungsten and other metal elements are added on this basis. It is generally produced by the powder metallurgy method. The electrical conductivity is excellent, and they provide a high level of thermal stability and a high mechanical strength. Besides, they are non-magnetic. All of these features make them be used in precision-machine, especially in where tungsten nickel iron alloys would cause magnetic interference.
Alfa Chemistry provides high-quality tungsten-nickel-copper alloys at a competitive price. Tungsten-nickel-copper alloys we can supply are in the shapes of rod, ball and plate, etc. We can also customize various shapes of tungsten-nickel-copper products according to your requirements or drawings.
