FeCrCo Magnet

Iron chromium cobalt permanent magnets can be magnetized by plane octapole, multi-pole magnetized by plane, and has the advantage of being machined. It is especially suitable for small and thin permanent magnet components with complicated shapes and sizes. Can be used in telephones, tachometers, micro motors, micro relays, speakers, etc.

Discriptions of Features

1. Properties of FeCrCo permanent magnet alloy are close to properties of permanent magnet alloy.
2. FeCrCo permanent magnet alloy has good machining performance, and can be drilled、planed、weared、stampted and other machining operations.
3. FeCrCo permanent magnets can be made into small 、slender componets of various shapes, the minimum wire diameter can be up to 0.05mm, the thickness of thinnest strip is only 0.1mm.
4. FeCrCo permanent magnet alloy has excellent temperature stablity、good corrosion resistance and high curie temperature(about 680℃), the maximum working temperature is 400℃.
