Resistance Welding Copper Tungsten Electrode For Tungsten Electrodes
The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make tungsten copper alloy very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.
Tungsten copper electrode is a good use of high-purity tungsten metal powder and high purity characteristics of the plasticity of copper powder, the advantages of high conductivity, the static pressure molding, high temperature sintering, melting refined copper from the process of composite materials. Arc off a good performance, good thermal conductivity, thermal expansion of small, high-temperature non-softening, high-intensity, high-density, high hardness.
Grade: tungsten copper alloy rod and bar
