Because pure tungsten is expensive and difficult to manufacture and machine, alternative materials were sought which would maintain some of the useful characteristics of tungsten, such as density and X-ray shielding capabilities, but which would be easier to machine and less expensive. The result of this quest are the Heavy Tungsten Alloys.

Tungsten heavy alloys are ideal for high-density applications or for use in radiation shielding. Heavy metal tungsten alloys are 90% to 97% pure tungsten in a matrix of nickel/copper or nickel/iron. MTS can custom machine any alloys to finished parts according to your specifications. We carry an extensive inventory of tungsten alloys and provide quick turnaround for those items not in stock.

Tungsten Copper Alloy Advantages

• High arc resistance combined with good electrical conductivity
