FeCrCo & Crovac
Descriptions of products
FeCrCo/Crovac as a new type magnet has come into the world in 1970’s. It is widely used in space, aviation, shipping instrument, automobile instrument, magnetic motor, compass, computer embroider machine and signal system etc.
FeCrCo/Crovac has good plasticity, ductility and machining ability. And can be drilled, planed, stamped and other machining operations. The minimum diameter can be 0.05 mm and the thickness of strip can be 0.1 mm, especially suit for tinny elements with accurate dimensions and complicated shapes, such as strip, wire, bar and tube etc.
FeCrCo/Crovac has excellent temperature stability, good corrosion resistance and high curie temperature(around 680℃). The maximum working temperature is 400℃.
