Scope*1.1 This specification establishes the requirements

3、for man-ganese bronze rod, bar and shapes produced in Copper AlloyUNS Nos. C67000, C67500, or C67600.1.2 The values stated in inch-pound units or SI units are tobe regarded separately in the standard. Within the text, the SIvalues are given in brackets. The values stated in each systemof units are n

4、ot exact equivalents; each system is independentof the other. Combining values from the two systems mayresult in nonconformance with the specification.1.3 The following safety hazard caveat pertains only to thePerformance Requirements section of this specification. Thisstandard does not purport to a

Material and Manufacture5.1 MaterialThe material of manufacture shall be castbillet

18、s of Copper Alloy UNS No. C67000, C67500, or C67600as specified in the ordering information, and shall be of suchpurity and soundness as to be suitable for hot working.5.2 Manufacture:5.2.1 The product shall be manufactured by hot working(extrusion, forging, or rolling) to produce a uniform wroughts

19、tructure in the finished product.5.2.2 The product shall be finished by such cold working,annealing, and straightening as may be necessary to achievethe required properties.6. Chemical Composition6.1 The material shall conform to the chemical compositionrequirements in Table 1 for the Copper Alloy U

20、NS No.specified in the ordering information.6.1.1 These compositional limits do not preclude the pres-ence of other elements. By agreement between the manufac-turer and the purchaser, limits may be established and analysisrequired for unnamed elements.6.2 For copper alloys in which zinc is specified

24、ecified in the contract or purchase order, theproduct shall be tested for residual stress according to therequirements of Test Method B 154 or Test Method B 858 andshow no signs of cracking. (WarningMercury is a definitehealth hazard. With the mercurous nitrate test, equipment forthe detection and r

25、emoval of mercury vapor produced involatilization is recommended. The use of protective gloves forthis test is recommended.)9.1.2 When the ammonia vapor test is used, the test pHvalue appropriate for the intended application shall be 10unless otherwise specified by the purchaser.NOTE 2Aresidual stre

26、ss test provides information about the adequacyof the stress relief of the material. Bar straightening is a method ofmechanical stress relief.
