Magnetic Core Powder

The magnetic core powder is based on FeSi, and different alloy powders are developed for different applications such as high frequency and high current through composition optimization design, so as to ensure that the formed products have excellent DC bias and low loss characteristics. Because of its high sphericity and low impurity content, Fe Si soft magnetic alloy powder is more suitable for high-end magnetic powder core and other occasions with high requirements for powder coating. It is widely used in PFC choke coil, reactor, APF inductor and other devices. Chemical Composition（wt%） Grade Si Al Ni C O S P Fe FeSi 3.2-3.8 - - ≤0.03 ≤0.06 ≤0.01 ≤0.02 Bal.
