RWMA Class 12 Tungsten 80% – Copper 20%, Suited For Electro-forming And Electro-forging Facings
Description:
For resistance welding, the parts will be pressed and heated under high current until the parts are joined together.
And for welding, the force between the electrode and the parts are large. Some of them can reach to 450 MPa.
Uncer this process, it rises great challenge for the welding electrodes.
We make welding electrodes from refractory metal like tungsten, molybdenum, tungsten alloy and molybdenum alloy.
These refractory metals have high melting point which can withstand high temperature and they also have good electrical conductivity.
TUNGSTEN 80% – COPPER 20%, suited for electro-forming and electro-forging facings, and for electrode facings used to upset studs and rivets. A material for heavy-duty projection welding electrodes.
For joint method between shaft and our refractory metal, we can offer braze welding and also back casting.
Our products can be used for spot welding, projection welding and also thermode welding.
