Description of ASTM-B888 2012ASTM B888 - 12Standard Specification for Copper Alloy Strip for Use in Manufacture of Electrical Connectors or Spring ContactsActive Standard ASTM B888 | Developed by Subcommittee: B05.01 Book of Standards Volume: 02.01 ASTM B888Abstract This specification establishes the requirements for copper alloy strips for use in the manufacture of electrical connectors or spring contacts produced from one of the following Copper Alloy UNS Nos.: C14530, C15100, C15500, C17000, C17200, C17410, C17450, C17460, C17500, C17510, C19010, C19025, C19210, C19400, C19500, C19700, C23000, C26000, C40810, C40850, C40860, C42200, C42500, C42520, C42600, C50580, C50780, C51000, C51080, C51100, C51180, C51980, C52100, C52180, C52480, C63800, C65400, C68800, C70250, C70260, C70265, C75200, and C76200. The material for manufacture shall be a cast bar, slab, cake, billet, or other form of such composition as to be suitable for processing by either hot- or cold-working to produce the products prescribed in this specification. Products shall be finished by hot working, cold working, annealing, or heat treatment as may be necessary to meet mechanical property requirements, which include tensile strength, yield strength, and elongation. Tempers shall be available in the annealed, rolled, or mill hardened conditions. Products shall also adhere to tolerances as to dimension such as thickness, width, length, straightness, and mass. This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 1. Scope 1.1 This specification establishes the requirements for copper alloy strip for use in the manufacture of electrical connectors or spring contacts produced from one of the following Copper Alloy UNS Nos. 2 : C14530, C15100, C15500, C17000, C17200, C17410, C17450, C17460, C17500, C17510, C19002, C19010, C19015, C19025, C19210, C19400, C19500, C19700, C23000, C26000, C40810, C40850, C40860, C42200, C42500, C42520, C42600, C50580, C50780, C51000, C51080, C51100, C51180, C51980, C52100, C52180, C52480, C63800, C64725, C65400, C68800, C70250, C70260, C70265, C70310, C75200, and C76200. 1.2 The requirements for the other copper alloys such as copper-nickel-tin spinodal, UNS C72650, C72700, and C72900, shall be as prescribed in the current edition of Specification B740 . 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
