Tungsten Copper Rod
Tungsten Copper Rods are a tungsten copper alloy refined by powder pressing, static pressing, high temperature sintering, melting, and other processes using high-quality tungsten copper mixed materials, which are suitable for resistance welding electrodes, TIG welding, MIG welding, EDM processing, etc.
Tungsten Copper Rods have high electrical conductivity, high hardness, high temperature resistance, corrosion resistance, high welding quality, low thermal expansion coefficient, wear resistance, fast processing rate, high heat dissipation performance, it is often used in heavy projection welding, non-ferrous metal welding or electrobrazing welding environments such as cross wire welding and cross welding of large diameter wires and bars.
