Production

Principal Applications

These powder are mostly used in the manufacturing of diamond segments by hot pressing as additives in the metal matrix to improve the diamond retention and cutting ability. Also, these powders are used to manufacture electrical contacts, copper tungsten electrodes, weight fillers, induction accelerators, radiation shielding fillers and counter balance. Higher density Tungsten powder used for plastic densifier.
