An overview of the powder processing of soft magnetic composites

The technique of powder metallurgy is becoming increasingly common in the electrical manufacturing industry. It not only eliminates a number of steps in the manufacturing process, but uses less energy and gives near-net shape results which require few, or no finishing steps. The process is suitable for soft magnetic composites, and appropriate heat treatments can further tailor properties to a specific application. This article gives an overview of the technology and makes reference to some advances in the materials used and the processes involved
