Fe-Cr-Co magnets are composed of Iron, Chromium and Cobalt elements. The significant advantage of Fe-Cr-Co magnets is the low-cost shaping possibilities.
Fecrco magnet is a new type has come into the world in the 1970’s, offers the high permanent magnetic property . It has excellent temperature stability、good corrosion resistance and high curie temperature(about 680℃), the maximum working temperature is 400℃. FeCrCo permanent magnets can be made into small , slender components of various shapes, the minimum wire diameter can be up to 0.05mm, the thickness of thinnest strip is only 0.1mm.
