Tungsten copper W70 block 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.
Tungsten copper W70 block has excellent mechanical strength and electric erosive resistance.
It can be widely used for vacuum contacts, transformer switch and some infiltration or electrical forging industries.
| The standard length and width of tungsten copper block we are able to provide is less than 300mm, and the thickness is more than 0.1mm (±0.05mm), customized sizes and tolerances are also accepted.
