Copper tungsten alloy tube is a kind of tungsten copper alloy product that 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. Composition proportion of tungsten copper alloy tube small diameter is 60/40 (60% Tungsten, 40% copper) composition. Composition proportion of tungsten copper alloy tube with rather big diameter is 70/30 (70% tungsten, 30% copper).
