Scope of standard 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:Alloy TypeUNSNominal Composition1R3000549 % Co, 49 % Fe, 2 % V2K9265027 % Co, 0.50 % Cr, balance Fe1.1.1 This specification also 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, 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 customary (cgs-emu and inch-pound) units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.
