W75 tungsten copper features: tungsten copper is the use of high purity tungsten metal powder excellent features and advantages of high purity copper powder plasticity, high electrical conductivity, the static pressure molding, high temperature sintering process of copper, soluble permeability composite materials refined but become. Arc breaking performance is good, good conductive heat conduction and thermal expansion of small, high temperature softening, high strength, high density, high hardness. Purpose: 1. Resistance welding electrodes, taking advantages of tungsten and copper, high temperature resistance, arc ablation resistance, high strength, better than major, conductive, thermal conductivity, easy to machining, and has the characteristics such as sweating ling but, because of its high hardness, high melting point, resistance of tungsten adhesion characteristics, often used to make a certain wear resistance, resistance to high temperature of projection welding, butt welding electrode.
