Powder metallurgy is the process of forming press metal powder which is heated to just below its melting point. Powder metallurgy is a technology that requires a lot of time and effort to convert the starting material into the required powder form, and then more time and effort to "glue" the material to a more or less dense object to obtain. The powder metallurgical process (PM) shown in the following figure involves mixing the powdered elements or alloys, compacting the mixture in the nozzle, and then sintering or heating the resulting shape in an atmosphere-controlled furnace to metallurgically bind particles. Powder metallurgy is the main engine of the structural (or mechanical) sector. Powder metallurgy wins cost competition due to lower energy consumption, higher use of materials, and a lower number of process steps compared to other production technologies. Basically, powder metallurgical efficiency also requires that specific products be produced in large quantities.
