Carpenter Technology manufactures semi-hard and hard magnet alloys that are ductile and can be fabricated by bending, drawing, cold rolling, machining and stamping. After fabrication, these alloys require a final heat treatment to achieve the desired magnetic characteristics.

These alloys can provide versatile alternatives to higher coercivity materials which, although they provide the magnetic properties required for countless applications, are difficult to fabricate because of their brittleness. Also, some of the higher coercivity materials may exhibit poor corrosion resistance and less than desirable temperature stability.

CarTech Chromindur II is a ductile, permanent magnet alloy. In the solution treated condition, it is capable of being cold rolled, formed, drilled, machined, etc.

Aging the alloy results in a spinodal decomposition resulting in a structure similar to AlNiCo magnets but with much lower cobalt content.

Applications:
Ductile Magnetic alloys have been used for biasing magnets in meters and magnetic actuators, as magnetic coded devices, field coils for DC motors and servos, and hysteresis motor laminations.
