Materials shall be processed by hot working, cold working, and annealing as to produce a uniform wrought structure in the finished product. Tempers shall be available in the rolled, as hot rolled, or annealed conditions. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, mass, straightness, and edges), mechanical (tensile strength, and Rockwell hardness), chemical composition, and grain size requirements.1.1 This specification establishes the requirements for specified copper-zinc-tin alloys and copper-zinc-tin-iron-nickel alloys plate, sheet, strip, and rolled bar. The alloys and nominal compositions are as follows:Copper AlloyUNS No. Copper,% Tin,% Zinc,% Phos.,% Iron,% Nickel,% C40500 95 1 4 C40810 95.5 2.0 2.2 0.03 0.1 0.15C40850 95.5 3.0 1.3 0.1 0.1 0.1C40860 94.8 2.0 3 0.03 0.03 0.1C41100 91 0.5 8.5 C41300 91 1 8 C41500 91 2 7 C42200 87 1 12 C42500 88 2 10 C42520 89.8 2.0 8 0.1 0.1 0.1C43000 85 2 13 C43400 85 0.7 14.3 1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.2.1 Exception—Average grain size in Table 3 is stated in SI units.1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification:1.3.1 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This specification concerns general procedures for specifying requirements of flat-rolled electrical steels for magnetic applications. This specification is to be used when the material in question is not covered by an ASTM material specification. The specification does not contain requirements but instead lists physical properties, ordering information and other attributes that should be considered when purchasing the material. All ASTM electrical steel specifications are in conformity to this specification.1.1 This specification covers general procedures for specifying requirements in the procurement and delivery of flat-rolled electrical steels for magnetic applications. When an applicable individual specification does not exist, this specification enables the user to order a suitable material to be supplied under controlled conditions with respect to magnetic quality, sampling, testing, packaging, and so forth, by specifying certain requirements on the purchase order and citing this specification.1.2 Individual ASTM electrical steel specifications that are in conformity with this specification are Specifications A677, A683, A726, A840, A876, and A1086.NOTE 1: For more information on other standards associated with this specification, refer to the following: Test Methods A341/A341M, A343/A343M, A348/A348M, A596/A596M, A712, A717/A717M, A719/A719M, A720/A720M, A721/A721M, A773/A773M, A804/A804M, A889/A889M, A937/A937M, A971/A971M, and Practice A664.1.3 The values stated in SI units are to be regarded as standard.
