(Specification)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
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 for Copper Alloy UNS Nos. C19002, C19010, C19015, C19020, C19025, C63800, C64725, C70250, C70260, C70265, and C70310 sheet and strip.
1.2 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.
1.3 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.
