Powder metallurgy (PM) is a unique, highly developed method of manufacturing ferrous and nonferrous parts. It is a versatile, cost-effective, and constantly expanding technology that is rapidly gaining worldwide popularity. The PM process begins with thorough blending of carefully weighed powdered metals or alloys to produce uniform distribution of the particles. Typical metal powders include bronze, brass, nickel, silver, iron-nickel and various grades of stainless. The resultant blends may include specified quantities of die lubricants, graphite, and other additives.
