Common Uses of Tungsten Copper Alloy Rods
1. Electrode Material: Used for EDM Electrospark Machining Electrode. The surface finish of the electro-machining product is high, the precision is high, the loss is low, and the cost is effectively saved.
2. Contact Material: Arc contact and vacuum contact of high and medium voltage switch or circuit breaker, circuit board welding and electrical contact point.
3. Welding Material: Resistance welding electrode
