Copper tungsten contact parts find applications in SF-6 circuit breaker, load break switches, transformer step switches [OLTC], resistance welding electrode and spark erosion electrodes.
As there is a huge distance between the tungsten and copper of the melting point, so we can adopt high temperature liquid sintering method to make tungsten copper alloy, through which densification its density at the temperature higher than copper melting point.
