Fine selection of tungsten copper tungsten, copper powder, the sintering soak refined class, affordable, moderate and high stress of nearly 2,000 high, with a high melting point, high hardness, anti-burning and good anti-stick 
 Attached, electrical corrosion products, surface finish, high precision, low loss. 
 Tungsten and copper is widely used as high-pressure, super-hydraulic switch and circuit breaker contacts, protection ring, for the electric upsetting anvil block of material, conductive nozzle submerged arc welding, plasma cutting machine nozzles, welding machine, welding machine, welding the first , roll welding wheels, electrode and the point of sealing gas Mao spark electrodes, spot welding, butt welding materials. 
 Tungsten W = 70 Cu Cu = 30 conductivity% IACS ≥ 42 Density = 14g/cm3 softening temperature ℃ ≥ 700 ≥ 184HV hardness, tensile strength ≥ 66Mpa 
 Tungsten and copper by isostatic pressing - sintering tungsten skeleton - dissolved copper infiltration process, is an alloy of tungsten and copper. 
 1. Resistance welding electrode: a combination of the advantages of tungsten and copper, high temperature resistance, arc erosion, high strength, heavy, electrical conductivity, thermal conductivity, and easy machining, and so on with transpiration cooling 
 Characteristics, because of its high hardness of tungsten, high melting point, anti-adhesion characteristics, often used to make a certain wear resistance, high temperature welding, welding electrodes. 
 2. EDM Electrode: tungsten steel for high temperature super-hard alloy die to be produced by electrical erosion, the common electrode wear big and slow. The tungsten and copper corrosion, high speed, low loss rate, 
 Exact electrode shape, excellent processing performance, to ensure the accuracy of parts to be machined greatly increased. 
 3. High-voltage discharge electrode: high-voltage vacuum discharge tube at work, the contact material in a few seconds of time zero temperatures thousands of degrees Celsius. The W-Cu high ablation resistance, high 
 Toughness, good electrical conductivity, thermal conductivity and stability to the discharge tube to provide the necessary conditions. 
 4. Electronic Packaging Materials: Tungsten, low expansion characteristics of both, but also has high thermal conductivity properties of copper, the thermal expansion coefficient and thermal conductivity of conductive material can be adjusted to change the composition and,
