Standard Specification for Copper-Zirconium Alloy Sheet and Strip

2020-04-20 /Active

This specification establishes the requirements for sheets and strips of copper-zirconium alloys with Copper Alloy UNS No. C15100. The material for manufacture shall be a cast bar, slab, cake, billet, or others 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 sampled and prepared, then tested accordingly to examine their conformance to dimensional (thickness, length, width, mass, straightness, and edges), mechanical (tensile strength, and hardness), electrical resistivity, chemical composition, and grain size requirements.


1.1 This specification establishes the requirements for Copper Alloy UNS C15100 sheet and strip.

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—Values given in inch-pound units are the standard except for grain size, which is stated in SI units.

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.
