Abstract
A process for forming particulate tungsten heavy alloys from agglomerated material containing the individual metals by using a high temperature zone is improved by retaining the material in the high temperature zone for a time sufficient to at least partially melt the metals that are alloying with tungsten while maintaining the temperature of those metals below the boiling point of the lowest boiling metal in the alloying component.
