Product Description

UNS K92650 Wrought Iron-Cobalt High Magnetic Saturation Alloy



K92650 is a rought iron-cobalt alloy used in magnetic components requiring high permeability at and above 15 kG (1.5 T) or high magnetic saturation.

ASTM A801 covers material supplied by a producer in the form and physical condition suitable for
fabrication into parts that will later be given final heat treatment to achieve the desired magnetic characteristics and, where required, mechanical properties. It covers material supplied in form of forging billets, hot-rolled products (that is, bar, plate, and strip), cold-finished bars, and cold-rolled strip. But it does not cover parts produced by casting or by powder metallurgical techniques.

Heat treatment

K92650 is typically heat treated between 845 and 865°C for the best magnetic performance. It may also be heat treated at temperatures as high as 975°C.
