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.
FeCrCo magnets, a new type has come into the world in the 1970's. These magnets' properties are featured with higher permanent magnetic property, comparable to those of cast AI-NI-CO magnets, and with a good ductility in the as-quenched state, but with Co content 50% smaller than AINICO magnet. FeCrCo machinable permanent magnetic alloy is also famous for its great plasticity, ductility and machinability, this performance far better than casting permanent magnetic alloys, while its high working temperaure outshines that of NdFeB permanent magnet. They can be made into semi-hard magnetic alloy, especially suitable for making the small and thin elements with accurate dimensions and complicated shapes, such as wire, tube, bar, strip, etc.

Detailed Description
Feature:
Fe-Cr-Co alloy has a big advantage, namely its high Curie temperature, Tc = 680ºC for the left and right (Tc slightly different in different alloy grades) so that its temperature can reach 400ºC, reversible temperature coefficient is small, is -0.0128%ºC, the magnetic stability of the well for the high-precision components.
