Powder Metallurgy (PM) is a form of sintering. Individual engineering components are produced directly by the process and referred to as sintered components / parts, or PM parts.
Processed products also can be generated from powder and scientifical developments of great industrial potential are in a steady process.
In order to producing a compact having sufficient cohesion enabling it to safe handling the powder is compressed, usually in a container, and heated afterwards to a temperature below the melting point of the main constituent. Due to this process the individual particles weld together and confer sufficient strength on the material for suitable use. This heating step is referred to as sintering.
