Tungsten Copper W70 Rod
Description
Tungsten copper W70 rod is composed of 70% W and 30% Cu so that it is harder than W50 and W60 rods. Its density is up to 12.75g/cm3, hardness reaches more than HB140, and conductivity is 47%IACS, softening temperature is ≥900℃ and the bending strength is 790.
Features
Tungsten copper W70 rod belongs to refractory metal and has excellent mechanical strength and anti-arc ablation capability.
Applications
Used as the contacts, tungsten copper W70 rod has good mechanical properties and anti-seismic, which can be welding for supporting W-Cu contacts.
