【国外标准】 Standard Specification for Copper-Zinc-Tin and Copper-Zinc-Tin-Iron-Nickel Alloys Plate, Sheet, Strip, and Rolled Bar

This specification covers the requirements for plates, sheets, strips, and rolled bars of copper-zinc-tin and copper-zinc-tin-iron-nickel alloys with Copper Alloy UNS Nos. C40500, C40810, C40850, C40860, C41100, C41300, C41500, C42200, C42500, C42520, C43000, and C43400. 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. 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.1.4 This 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.
