Tungsten Series
Introducing the 90's modern facilities and technologies for tungsten manufacture from Europe and Japan, XMAM is committed to innovation and fast development. And we have developed a series of high qualified tungsten products such as bar, tube, rod, disc, contact, pins, wire, sheet, foil, boat, carbide, etc which are widely used for electronic and other industries. XMAM has been one of the leading tungsten products exporters in China from end of the 90's.

Tungsten-copper (silver) composites
We can produce tungsten-copper(silver) composites with 10-90% of copper(silver) with standard and special shape in different sizes. These products are manufactured by CIP forming, sintered tungsten skeleton and other infiltrating copper (silver) technology.
