Ø8x200mm tungsten copper rod with diameter of Ø8mm and length of 200mm, the general diameter tolerance is ±0.5mm and length tolerance is 0 to +5mm. As a contact material, it has very good machinability and thermal shock resistance. Due to arcing during contact and breaking, the contact material will rise by several thousand degrees Celsius in a fraction of a second.

Ø6x200mm tungsten copper rod with diameter of Ø6mm and length of 200mm, the general diameter tolerance is ±0.5mm and length tolerance is 0 to +5mm. It has good electrical and thermal conductivity, arc ablation resistance and high material erosion rate, especially in the corrosion of molds made of tungsten steel and high temperature resistant super hard alloys.

Ø7x200mm tungsten copper rod with diameter of Ø7mm and length of 200mm, the general diameter tolerance is ±0.5mm and length tolerance is 0 to +5mm. which has excellent mechanical strength and excellent arc erosion resistance. In practical applications, it is widely used in vacuum electrical contacts, transformer switch contactors, and some electric and electric forging industries.

Ø5x200mm tungsten copper rod with diameter of Ø5mm and length of 200mm, according to the content of tungsten and copper, the main proportion or grade of Ø5x200mm tungsten copper rod includes W50, W55, W60, W65, W70, W75, W80, W85, W90 and so on. Different proportions of tungsten and copper rods have different uses.
