Description / Abstract:



1. Scope

1.1 This specification covers two wrought iron-cobalt alloy types currently manufactured and supplied commercially for use in magnetic components requiring high permeability at and above 15 kG [1.5 T] or high magnetic saturation. The specific alloy types covered are:

1.1.1 This specification also covers material supplied by a producer or converter 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, cold-finished bars, and strip.

1.2 This specification does not cover parts produced by casting or by powder metallurgical techniques.

1.3 The values stated in either customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
