ASTM A801 Soft Magnetic Alloys HiperCo27 High Saturation Induction Cold Rolled Strip

HiperCo27 High Saturation Induction Soft Magnetic Alloy Round Bar

HiperCo27(UNS K92650) is named 1J27 in China. It is a new type of soft magnetic alloy in China even it is already widely introduced by the inventor Carpenter. A-one Alloy is among the several manufacturers who are able to produce HiperCo27 products in forms of cold rolled strip and round bar.

HiperCo27 is a better choice when the fabrication is considered when HiperCo50 is somehow has better permeability and coercive force-even the difference is not big. The magnetic saturation of both alloys is nearly identical. And, Hiperco 27 does not exhibit the brittleness of Hiperco50.
