70/30 Copper Tungsten alloys are commonly used in electrical discharge machining applications, electro chemical machining applications, and a variety of welding applications too. The material can be used for flash and butt welding die inserts, spot welding ferrous metals, and stainless-steel welding applications where the electrode requires a higher electrical conductivity than the workpiece.

75/25 Copper Tungsten alloys are the industry standard when it comes to flash welding and butt welding die inserts, especially when the welding pressures are low to moderate. The 75/25 variety is also suitable for electro forming dies, seam welding brush inserts, and the spot welding of ferrous metals. Copper Tungsten 75/25 can also be used as an electrode material for electrical discharge machining applications.

80/20 Copper Tungsten alloys are suitable for projection welding dies where welding pressures are relatively high. This particular blend of alloy is also used for electrical upsetting of nonferrous metals and low-carbon steel. The use of 80/20 Copper Tungsten is also popular when doing cross wire welding of wires and rods.
