The magnetic ring needs to be painted to facilitate the distinction. Generally, the iron powder core is distinguished by two colors. The commonly used ones are red/transparent, yellow/red, green/red, green/blue and yellow/white. The manganese core ring is generally painted with green. , Iron, silicon and aluminum are generally all black and so on.
In fact, the color of the magnetic ring after firing has nothing to do with the dyeing of the paint sprayed later, it is just an agreement in the industry. For example, green represents high permeability magnetic ring; two-color represents iron powder core magnetic ring; black represents iron-silicon-aluminum magnetic ring and so on.
(1) High magnetic permeability ring, we have to say nickel-zinc ferrite magnetic ring. The magnetic ring is divided into nickel-zinc and manganese-zinc according to the material. The magnetic permeability of nickel-zinc ferrite magnetic ring materials is currently used ranging from 15-2000. The commonly used material is nickel-zinc ferrite with a magnetic permeability of 100- Between 1000, according to the magnetic permeability classification, it is divided into low magnetic permeability materials. The magnetic permeability of manganese-zinc ferrite magnetic ring material is generally above 1000, so the magnetic ring produced by manganese-zinc material is called high permeability magnetic ring.
(2) Iron powder core magnetic ring: Iron powder core is a common term for magnetic material ferric oxide, which is mainly used in electrical circuits to solve electromagnetic compatibility (EMC) problems. In practical application, various other substances will be added according to different filtering requirements in different frequency bands.
(3) The 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 on the cross-sectional area of the magnetic core. The average maximum magnetic 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, very stable performance at high temperature.
