FeSiCr
FeSiCr alloy powder is a soft magnetic material developed by adding chromium element to iron-silicon alloy. It has good thermal stability, wear resistance, excellent compressive strength along with stable chemical composition & properties. This material combines high saturation magnetic flux density of iron-silicon alloy with outstanding corrosion resistance and high-frequency performance imparted by chromium and is made as soft magnetic powder via high-pressure water atomization or gas atomization powder metallurgy technology.
