W75Cu25 Copper Tungsten Bar For Electric Spark Welding Low Thermal Expansion

Low Thermal Expansion W75Cu25 Copper Tungsten Bar For Electric Spark Welding

Copper Tungsten Bar is an alloy of tungsten and copper. Tungsten copper alloy is made of fine tungsten and copper powder through the first-class immersion sintering process and the process of isostatic pressing - high-temperature sintering tungsten skeleton - copper infiltration.

Specifications of Copper Tungsten Bar

Copper Tungsten Bar Picture:

Physical properties of Copper Tungsten Bar

• Tungsten copper alloy (tungsten W=70 copper Cu=30)

• Conductivity% IACS ≥ 42

• Density=14g/cm3

• Softening temperature ℃ ≥ 700

• Tensile strength ≥ 66Mpa

• Hardness ≥ 184HV

• Tungsten copper alloy can withstand nearly 2000 ℃ high temperature and high stress. It has the characteristics of high melting point, high hardness, resistance to burning and good resistance to adhesion. The surface finish of electric erosion products is high, the precision is extremely high, and the loss is low.

Applications of Copper Tungsten Bar

• Tungsten copper alloy is widely used as the contact and protective ring of high-voltage and superhydraulic switches and circuit breakers, the material of electric heating block block, the conductive nozzle of automatic submerged arc welding, the nozzle of plasma cutting machine, as well as the welding head of electric welding machine and butt welding machine, the roller welding wheel, as well as the materials for making sealing gas socket electrode and electric spark electrode, spot welding, butt welding, etc
