The tungsten content in commonly used tungsten-molybdenum alloys is 30% to 50% (mass). The preparation method of tungsten-molybdenum alloy is the same as that of metallic molybdenum materials and molybdenum alloys, that is, powder metallurgy sintering post-processing and smelting processing. Rods, plates, wires or other profiles can be produced.
Tungsten-molybdenum alloy containing 30% (mass) of tungsten has excellent resistance to the corrosion of liquid zinc and is used to manufacture mixers, pipe and vessel linings and other components in the zinc smelting industry. Tungsten-molybdenum alloy has good high-temperature strength, similar performance to tungsten and smaller specific gravity than tungsten. Therefore, it can be used as high-temperature components in rockets and missiles, filaments and parts of electron tubes and other high-temperature materials under corresponding high-temperature conditions.
