FeCrCo Magnets

FeCrCo magnet is made of iron, chromium, cobalt and few other elements like molybdenum, silicon. It was appeared in the early 1970s at the first time. The magnetic performance of FeCrCo permanent magnet is similar to that of Alnico 5 permanent magnet.

The most prominent feature of FeCrCo magnet is its excellent machining performance. FeCrCo permanent magnets are easily made into small, thin and complex-shaped components. The wire diameter of FeCrCo alloy could be made as small as 0.05mm, and the strip thickness could be made to 0.1mm, which are suitable for making precise components.
