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.
