4. Application Of WCu Tungsten Copper Alloy Rod Bar:
Tungsten copper alloy rod has excellent mechanical properties and electrical and thermal conductivity, and has broad application prospects in electrical processing and electrical contact materials. Especially in the field of electrodes, such as EDM electric discharge machining clicks, resistance welding electrodes, high voltage discharge tube electrodes, etc. have played an important role.
EDM electrodes
Tungsten copper EDM electrode rod has good electrical and thermal
conductivity, arc ablation resistance and high material erosion
rate, especially for tungsten steel, high temperature resistant
super hard alloy molds have significant advantages.
Resistance welding electrodes
The tungsten copper resistance welding electrode rod has good
electrical and thermal conductivity. It uses the resistance heating
effect generated by the current flowing through the contact surface
of the workpiece and the adjacent area to heat it to a molten or
plastic state to form a metal bond. Its main function is to press
the welding part with high pressure, provide a large amount of
welding current at the welding part and promote the cooling of the
welding part.
Discharge tube electrode
The discharge tube is a component used for high voltage protection
at the input end. When the voltage at both ends is higher than the
protection specification value, there will be a short circuit
inside, and the input overvoltage will be absorbed. The electrode
rod of tungsten copper discharge tube is made of fine high-purity
tungsten powder and high-purity tungsten-copper powder.
5. Precautions Of WCu Tungsten Copper Alloy Rod Bar:
Attention should be paid to the appearance of W60 tungsten copper
round rods: the appearance of products processed by tungsten copper
milling machine, lathe processing and grinding machine is
different, which is a normal phenomenon. The tungsten copper bar is
steel (black) color after fine grinding by a coreless grinder, and
copper (red) color after semi-fine (rough) grinding. This kind of
appearance is a normal phenomenon. Usually, small tungsten steel
round bars are processed by a coreless grinder, and large bars are
processed by a lathe. Plates are processed by milling or grinding
machines.
