Standard Specification for Copper-Zinc-Aluminum-Cobalt Alloy, Copper-Zinc-Tin-Iron Alloy Plate, Sheet, Strip, and Rolled Bar

2020-04-09 /Active

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.2

Note 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.
