P6 is a ductile, cobalt base precipitation hardened semi-hard magnetic alloy, similar to Vicalloy, combining the advantages of high hysteresis loss and low magnetizing force into one material. It exhibits the highest efficiency (loss per unit magnetizing force) of any known material.
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.
