Soft magnetic components
Soft magnetic composites (SMCs) are manufactured by pressing electrically-insulated iron-based metal powders into parts. They are typically used in electric motors. While sintering is not required, a thermal stabilization or stress-relieving treatment is usually carried out to obtain optimum magnetic characteristics.
Metal powders provide several benefits over more traditional materials such as laminated steels and permanent magnets:

Cost savings
By replacing a laminated component with a complex shaped formed by SMC, you could significantly decrease the quantity of copper wire used to keep the motor turning. This change alone directly translates into important weight reduction and, in turn, cost savings for the end user.

Fabrication flexibility
SMC have a high degree of flexibility when fabricating complex-shaped parts. Using SMC in the component manufacturing process, improves motor efficiency with high-torque density.

Lower losses at high frequencies
SMC materials have a high flux density, and so allow for lower electrical losses. This results in greater efficiency. In addition, there is less heat loss and higher power—meaning higher efficiency for your process.

3D part production
Using SMC in multi-material three-dimensional printing fabrication provides a way for manufacturing soft magnetic devices with complex structures in a single step. Particles can be formed into shapes allowing for 3D magnetic flux With soft laser sintering, SMC work by fusing layers in a powder bed which can be used to process polymers, metals, and ceramics. Magnetic properties of the nanoparticles are not influenced by this powder bed fusion process, making it a suitable process for 3D-printed objects.
