Iron, silicon and aluminum are generally all black.
FeSiAl magnetic ring is one of the magnetic rings with high usage rate. In simple terms, FeSiAl is composed of aluminum-silicon-iron and has a relatively high Bmax (Bmax is the average maximum magnetic flux on the cross-sectional area of ​​the magnetic core. Flux density.), its magnetic core loss is much lower than iron powder core and high magnetic flux, has low magnetostriction (low noise), is a low-cost energy storage material, no thermal aging, can be used to replace iron powder core , the performance is very stable at high temperature.
