1.1This specification covers two wrought iron-cobalt alloy types for use in magnetic components requiring high permeability at and above 1.5 T (15 kG) or high saturation flux density. The specific alloy types covered are:
| Alloy Type | UNS | Nominal Composition |
| 1 | R30005 | 49 % Co, 49 % Fe, 2 % V |
| 2 | K92650 | 27 % Co, 0.50 % Cr, balance Fe |
1.1.1This 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 (that is, bar, plate, and strip), cold-finished bars, and cold-rolled strip.
1.2This specification does not cover parts produced by casting or by powder metallurgical techniques.
1.3The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.
1.3.1There are selected values presented in two units, both of which are in acceptable SI units. These are differentiated by the word “, or,” as in “g/cm3, or, (kg/m3).”
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
