Abstract
Non-toxic shot having 40-60% tungsten, 20-60% tin and 0-10% iron. A process of formulating the material is disclosed in which 95% by weight of the particles of each component having mesh sizes less than 325 are blended with a flux having 99.9% by weight particles less than 100 mesh. The blended material is then compaction formed into shape at a pressure range of between 20 and 40 tons per square inch. Finally, the blended material is sintered at a temperature in the range of 350 and 425° F. bonding the powdered metals and driving off the flux.
