Powder metallurgy (PM) is one of the most interesting and innovative manufacturing technologies to arise since the turn of the 20th century, though its beginnings were as trying as they were auspicious. Despite its relatively recent entrance into the production sector of the modern economy, PM has been around for millennia in some form or other.
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.
