FeCrCo Magnets

FeCrCo magnets are made of iron, chromium, cobalt and small amounts of other elements such as molybdenum, silicon. It first appeared in the early 1970s. The magnetic properties of FeCrCo permanent magnets are similar to Alnico 5 permanent magnets.
 
The most prominent feature of FeCrCo magnets is their excellent machinability. FeCrCo permanent magnets are easily made into small, thin and complex shaped parts. The wire diameter of FeCrCo alloy can be as small as 0.05mm, and the strip thickness can be 0.1mm, which is suitable for making precision parts.
