1、Designation: B 98/B 98M 03Standard Specification forCopper-Silicon Alloy Rod, Bar and Shapes1This standard is issued under the fixed designation B 98/B 98M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision.

2、 A number in parentheses indicates the year of last reapproval.A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope *1.1 This specification establishes requirements for

3、copper-silicon rod, bar, and shapes for UNS Alloys C65100, C65500,and C66100.NOTE 1Material for hot forging is covered by Specification B 124.NOTE 2For ASME Boiler and Pressure Vessel Code applications, seeSpecification SB-98 in Section II of that code.1.2 The values stated in inch-pound units or SI

4、 units are tobe regarded separately as standard. Within the text, SI units areshown in brackets. The values in each system are not exactequivalents; therefore, each system shall be used independentlyof the other. Combining values from the two systems mayresult in nonconformance with the specificatio
