Powder metallurgy (P/M) has been used for manufacturing ferrous parts for over 80 years. The increase in P/M's usage has been positive for decades due to replacing parts previously made by machining and investment casting. The use of P/M in the jewelry and precious metal community has been limited and discontinuous. In the past several years interest has increased and there are now several P/M precious metal applications in production. This paper will describe these applications, the critical decisions leading to the use of P/M, and the constraints that have limited its use up until now.
