Cu-W alloy bar

Tungsten and copper powders are selected from high-purity fine tungsten and copper powder, refined by first-class immersion sintering process, with high melting point, high hardness, good anti-adhesion, high surface finish, high precision and low loss.

Used for high hardness materials (such as tungsten steel, quenched steel and other super hard metal), thin electrode discharge processing and spot welding, touch welding electrode.

Properties of Cu-W alloy: Combining the advantages of tungsten and copper, the Cu-W alloy is characterized by high temperature resistance, arc ablation resistance, high hardness, high melting point, high strength, high specific gravity, high conductivity, high thermal conductivity, free cutting, anti-adhesion, and sweat cooling. Our company adopts isostatic forming, high-temperature sintered tungsten skeleton and copper-permeating process to produce all kinds of large and special-shaped parts with copper content of 6-90%, with high purity, uniform organization and excellent performance. It can produce all kinds of sheet, rod, pipe, sheet and all kinds of products with complicated shape by die forming, extrusion forming and injection forming.

Uses of Cu-W alloy: because of tungsten high hardness, high melting point, anti-adhesion characteristics, often used to make a certain wear resistance, high temperature resistance projection welding, spot welding electrode. When the mould made of high temperature resistant superhard alloy of tungsten steel needs electric corrosion, the ordinary electrode loss is large and the speed is slow. The tungsten and copper with high corrosion rate, low attrition rate, accurate electrode shape and excellent machining performance can ensure the accuracy of the processed workpiece to be greatly improved.
