FeCrCo & Crovac
Product Details

  FeCrCo is one of machinable permanent magnetic alloy, which has good plasticity, ductility and machinability. It has the similar properties with Alnico5.  It can be made as different shapes and sizes such as wire, tube, bar, strip etc. 

  The alloy can be used at higher temperature and has good corrosion resistance. The high Curie temperature is about 680℃ and the highest working temperature can reach 400℃. 

FeCrCo is widely used in automobile instrument, aviation,shipping instrument, oil exploration, navigation, counter, signal produce system, magcard, security system, hydraulic locate gauge, compass, etc.

USA Standard- permanent cast FeCrCo magnet industry standard of USA (MMPA)
