Tungsten Copper W70 Rod
Introduction
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.
Characteristic
Tungsten copper W70 rod belongs to refractory metal and has excellent mechanical strength and anti-arc ablation capability so that it can be used for vacuum contacts, transformer switch and some electrical forging industries.
Application
As contact material, tungsten copper W70 rod has excellent mechanical properties and thermal shock resistance, which is suitable for various shape W-Cu contacts, such as copper, steel and other metal support connection, infiltrated or forged material and welding process.
