Tungsten Products: Tungsten Powder

Technical Data Sheet

Tungsten Powder has a number of valuable uses in today's world. Tungsten Powder is used in electrical contacts, airbag deployment systems, and as the beginning material in tungsten mill products and wire. Tungsten powder is also used in particle guns for genetic modification of plants and vegetables and in radiation compensators.

High purity tungsten powder is made for all these applications and more, and we are always interested in new applications. Please contact us if you are investigating a new use, or have any questions regarding tungsten powder.

All powder is commercially uniform in purity. The Chemical and Physical Analyses are determined for each production lot of powder by using commercially accepted methods. The results of all relevant tests are reported to the customer on a Certificate of Analysis.

Packaging

50 kg/100 lb packed in a polyethylene bag within a 3½-gallon plastic pail, or 250 kg/500 lb packed in a polyethylene bag within a 17-gallon drum, or as requested by the customer.
