ASTM B422/B422M-17

Standard Specification for Copper-Aluminum-Silicon-Cobalt Alloy, Copper-Nickel-Silicon-Magnesium Alloy, Copper-Nickel-Silicon Alloy, Copper-Nickel-Aluminum-Magnesium Alloy, and Copper-Nickel-Tin Alloy Sheet and Strip

ABSTRACT
This specification establishes the requirements for sheets and strips of copper-aluminum-silicon-cobalt, copper-nickel-silicon-magnesium, copper-nickel-silicon, copper-nickel-aluminum-magnesium, and copper-nickel-tin alloys with Copper Alloy UNS Nos. C19010, C19020, C19025, C63800, C64725, C70250, C70260, and C70265. Materials shall be tested and shall conform to dimensional (thickness, width, length, straightness, and edges), mechanical (tensile and yield strength, elongation, and ductility or formability), electrical resistivity, chemical composition requirements.
SCOPE
1.1 This specification establishes the requirements for2 Copper Alloy UNS Nos. C19002, C19010, C19015, C19020, C19025, C63800, C64725, C70250, C70260, C70265, C70310, and C70350 sheet and strip.  
1.2 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.  
1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification.  
1.3.1 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
