W75cu25 Tungsten Copper Alloy Bar
W75cu25 tungsten copper round bar is made of fine tungsten and copper powder, refined by first-class immersion sintering process, which can withstand high temperature of nearly 2000 degrees and high stress, with high melting point, high hardness, anti-burning and good anti-adhesion, electro-etched products with high surface finish, very high precision and low loss.
W75cu25 tungsten copper steel round bar is widely used as high-pressure, ultra-hydraulic switch and circuit breaker contacts, protection ring, for electric pier rough anvil material, automatic submerged arc welding conductive nozzle, plasma cutting machine nozzle, welding machine, welding head of the welding machine, roll welding wheel, sealing gas mortar electrode and point spark electrode, spot welding, touch welding materials, and so on.
