Coarse Tungsten Powder

tungsten powder

Introduction

Coarse Tungsten Powder is 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.
