FeSi

FeSi Characteristic

    Based on FeSi material, we develop a variety of alloy 

    powders for different uses, such as high frequency 

    and high current application, to make sure the molding 

    products have excellent DC bias and loss characteristics.

  • Applications
  • Core Loss Curves
  • Temp.Curves
  • Frequency Curves
  • DC Bias
