Usage:

Used for electrical spark erosion carving,

When we use hard alloy and queched mold steel for mold, we must use eletrical spark erosion equipment to carve the mold. If we using normal copper for spark eletrode, copper eletrode will be consumed fastly, and veracity can not be promised. But if we use tungsten copper material, the consumption of the eletrode will be reduced greatly, erosion speed will increased obviously, and veracity will be shift to much higher level.

 

To reach high veracity in spark erosion, we strongly recomand our tungsten copper electrode.
