Flat-FeSiAl

The series of flat FeSiAl soft magnetic alloy powders are a kind of soft magnetic alloy electromagnetic (EM) wave absorbing powders. They can be blended with various polymer materials to form raw compounds, which are then made into a variety of electromagnetic wave absorbing components through calendering, pressing, injection molding, extrusion and other processes.
