Fine Tungsten Powder
Introduction
The high quality and high purity fine tungsten powder are typically greater than 99.95% tungsten purity with average particle sizes up to 10 microns. These powders are used in powder metallurgy applications such as electrical contacts, heavy metal alloys, electronic heat sinks, mining tools and fabricated tungsten rod/bar.
