Thermal decomposition is most often used to process carbonyls. These powders, once milled and annealed, exceed 99.5% purity. The first step in the overall powder metallurgy process is making metal powders. There are four main processes used in powder production: solid-state reduction, atomization, electrolysis, and chemical.

The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various components. Close tolerance is possible for the components in the rolling. high-speed production takes place in the rolling.
