magnet material.
Fe-Cr-Co is one of machinable permanent magnetic alloy has good plasticity, ductility and machinability. It has the similar properties with AlNiCo. It can be produced into 0.05mm of strip and 0.1mm of wire. Our Fe-Cr-Co machinable permanent magnetic alloy is being used in shipping instrument, aviation, automobile instrument, compass, oil exploration, hydraulic locate gauge, signal produce system, security system, relay counter, computer-embroider machine, and hearing aid, etc. It can be made into semi-hard magnetic alloy and has good corrosion-resistance. The high Curie temperature is about 680. Simultaneity the alloy can be used at high temperature which can reach to 400.
