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.

This specification covers the requirements for plates, sheets, strips, and rolled bars of copper-zinc-aluminum-cobalt (Copper Alloy UNS No. C68800) and copper-zinc-tin-iron (Copper Alloy UNS No. C66300) alloys. The material for manufacture shall be a cast bar, cake, slab or so forth of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers H (rolled), and O (annealed to temper). Products shall be tested to examine their conformance to dimensional (mass, thickness, length, straightness, and edge), mechanical (tensile strength, and Rockwell hardness), electrical (resistivity and equivalent conductivity), chemical composition, and grain size requirements.1.1 This specification establishes the requirements for Copper Alloy UNS C66300 and C68800 plate, sheet, strip, and rolled bar.2NOTE 1: Since alloy C68800 is frequently used in a variety of applications where yield strength and stress-corrosion resistance may be critical, it is recommended that drawings or samples of the part to be fabricated and details of application be submitted for use in establishing temper and treatment of material.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, which are provided for information only and are not considered standard.1.3 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.
