A high density, non-magnetic alloy is described along with a process for manufacturing it. The preferred composition for the alloy is approximately 95% by weight of tungsten and 5% of austenitic stainless steel. The process for manufacturing the alloy begins with blending tungsten and stainless steel powders which are then mixed with an organic binder to form a feedstock. The latter is then molded into the form of compacted items, such as a hard drive counterweight balance, and then sintered in either vacuum or a hydrogen atmosphere. The tungsten heavy alloys of the present invention can be easily manufactured in large volume economically in many intricate shapes with excellent control of weight and dimensions.
