A
2、number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification establishes the requirements for man-ganese bronze rod, bar and shapes produced in Copper AlloyUNS Nos. C67000, C67
3、500, or C67600.1.2 UnitsThe values stated in inch-pound units or SI unitsare to be regarded separately in the standard. Within the text,the SI values are shown in brackets. The values stated in eachsystem of units may not be exact equivalents; therefore, eachsystem shall be used independently of the
4、 other. Combiningvalues from the two systems may result in nonconformancewith the standard.1.3 WarningMercury has been designated by EPA andmany state agencies as a hazardous material that can causecentral nervous system, kidney, and liver damage. Mercury, orits vapor, may be hazardous to health and
5、 corrosive tomaterials. Caution should be taken when handling mercury andmercury-containing products. See the applicable product Ma-terial Safety Data Sheet (MSDS) for details and EPAs website(http:/www.epa.gov/mercury/faq.htm) for additional informa-tion. Users should be aware that selling mercury
6、or mercury-containing products, or both, in your state may be prohibited bystate law.NOTE 1Product suitable for hot forging applications is availableunder Specification B124/B124M.1.4 The following safety hazard caveat pertains only to thePerformance Requirements section of this specification.1.4.1
7、This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Referenced Docum

Chemical Composition6.1
21、The material shall conform to the chemical compositionrequirements in Table 1 for the Copper Alloy UNS No.specified in the ordering information.6.1.1 These composition limits do not preclude the presenceof other elements. By agreement between the manufacturer andthe purchaser, limits may be establis
22、hed and analysis requiredfor unnamed elements.6.2 For copper alloys in which zinc is specified as the“remainder,” either copper or zinc may to be taken as thedifference between the sum of results for all other elementsdetermined and 100 %. When copper is so determined, thatdifference value shall con
23、form to the requirements given inTable 1.6.2.1 When all elements in Table 1 are determined, the sumof results shall be 99.5 % min.7.
