Copper Tungsten has the ability to provide stable cutting in carbide and other refractory metals. It is most widely used to machine tungsten carbide when fine surface finishes are required. Thin sheets, small diameter rods, and tubing are all 60/40 (60% Tungsten, 40% copper) composition. Plates, round bars and square bars are 70/30 (70% tungsten, 30% copper) composition.
