How to quickly determine the magnetic material of the inductor?



There are many kinds of inductive magnetic ring materials. According to different materials, they can be divided into iron powder core magnetic ring, carbonyl ferromagnetic ring, high magnetic flux core magnetic ring, iron silicon aluminum magnetic ring, iron and nickel molybdenum powder magnetic ring, soft magnet Oxygen magnetic ring, amorphous nanocrystalline alloy magnetic ring, etc. The industry is usually more accustomed to the use of 2 materials, 8 materials such as the name, to quickly distinguish between different magnetic ring material.


The method of quickly determining the magnetic ring material by the color of the inductor magnetic ring:


There are three types of iron powder magnetic ring: (yellow/white), (blue/yellow) or (green/blue), (gray/yellow)

The carbonyl ferromagnetic ring paint color: (full yellow) or (blue/white)

High-flux magnetic ring paint color: (all blue)

 

Iron-nickel molybdenum ring paint color: (all gray), (varnish)

Iron silicon aluminum magnetic ring paint color: (all black)

Nickel-zinc-ferrite magnetic ring is not painted rough surface, easy to drop powder, gray color

Manganese-zinc ferrite magnetic ring surface is not smooth, not easy to powder, dark

 


Amorphous nanocrystalline alloys are coated with full red, all blue, all white and other colors, which are clearly different from the above-mentioned coated seals.
