    Introduction


    Hiperco 27 alloy is an iron-cobalt-chromium soft magnetic alloy possessing the highest degree of ductility and toughness in the commercially available iron-cobalt grades of high saturation and high Curie temperature soft magnetic alloys. Although the permeability and coercive force of Hiperco 50 alloy are somewhat better than Hiperco 27 alloy, the magnetic saturation of both alloys is nearly identical. In addition, Hiperco 27 alloy does not exhibit the brittleness of Hiperco 50 alloy.

    Hiperco 27 alloy has been used in applications requiring a combination of good mechanical toughness, good ductility and high saturation induction. Examples have included motors, generators, pole pieces, relays and magnetic bearings.

    Table 4 Heat Treatment

    All stamped laminations or machined parts must be annealed after fabrication to develop acceptable magnetic properties. Anneal parts at 1400/1652°F (760/900°C) for 2 to 4 hours in dry hydrogen or vacuum and cool at 144/540°F (80/300°C) per hour until 572°F (300°C). All parts must be cleaned prior to heat treating.

    Table 5 Workability

    Hot Working

    Hiperco 27 alloy can be forged from a furnace temperature of 2150°F (1177°C). Time at temperature should be approximately 1 hour per inch of thickness. Forging can be conducted down to a temperature of 1700°F (927°C). After forging, items can be air cooled.
