FeSi (Iron Silicon) alloy powder is commonly & economically produced by atomization method. Owing to its high saturation flux density, low iron loss, good soft magnetic properties, relatively low cost, high production efficiency it is widely used in the field of magnetic materials, especially in powder metallurgy soft magnetic composite materials (SMCs). Its core advantage lies in the ability to flexibly balance magnetic properties and losses by adjusting silicon content and powder particle size, making it suitable for various application scenarios ranging from traditional power equipment to 3C chargers, new energy vehicles, charging piles, photovoltaic energy storage systems, and more.
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.
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.
