This specification establishes the requirements for UNS C61300 and C61400 copper aluminum bronze alloy sheets, strips, and rolled bars. These products are intended for drawing, forming, stamping, and bending applications but not for electrical applications. Each product is hot or cold rolled to finish gage and then annealed, if required, to meet the required temper properties. This specification also contains information on the required tensile strength, yield strength at extension under load, and elongation for different temper designations and product dimensions.

1.1 This specification2 establishes the requirements for Copper Alloy UNS Nos. C61300 and C61400 aluminum bronze sheet, strip, and rolled bar.

1.2 The products made to this specification are commonly used for drawing, forming, stamping, and bending applications and are not intended for electrical applications.

Note 1: The products produced under this general specification may be used in many applications in which the individual requirements may be too specific to be determined by normal physical or mechanical testing. Therefore, it may be advisable for the purchaser to submit samples or drawings to the manufacturer to be assured that the product furnished is suitable for the intended application.

Note 2: Refer to Specification B171/B171M for plate product.

1.3 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

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.
