(Specification)Standard Specification for Copper-Zinc-Silicon Alloy Rod
Standard Specification for Copper-Zinc-Silicon Alloy Rod
ABSTRACT
This specification establishes the requirements for rods of copper-zinc-silicon alloy with Copper Alloy UNS Nos. C69300, C69400, C69430, C69700, and C69710. The materials for manufacture shall be cast billets, logs, or rods of such purity and soundness as to be suitable for processing by cold working, annealing, straightening, and cutting to length as may be necessary to produce finished products that meet the properties specified. Tempers available under this specification are H02 (half hard) for UNS No. C69300, and H04 (hard) for all other UNS Nos. Products shall be tested (including by residual stress test and ammonia vapor test) and shall adhere to dimensional (diameter, length, straightness, and edge contour), mechanical (tensile and yield strength, and elongation), and chemical composition requirements.
SCOPE
1.1 This specification establishes the requirements for copper-zinc-silicon alloy rod produced in Copper Alloy UNS Nos. C69300, C69400, C69430, C69700, and C69710.
1.1.1 If the purchaser does not specify the alloy to be supplied, product is permitted to be furnished in any of the alloys named in 1.1.
1.2 Units—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 methods described in this specification. 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 requirements prior to use.
1.4 Warning—Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.
