Special Use Coarse Tungsten Powders

Coarse Tungsten Powders are:

Primarily intended for applications utilizing non-thermal powder consolidation technologies (tungsten– polymer/elastomer, deformable metal binder, etc.)
Special powder processing services available for narrow distribution, increased apparent density, and/or high flowability
Provides coarse particle size with low alkali metal content-ideal for thermal spray.
Widely used for lead-free ammunition and moldable radiation shielding products.
Useful as a pour-in high density filling material for irregular shaped cavities to add weight or radiation attenuation.

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