Standard Specification for Bronze Castings for Bridges and Turntables

ABSTRACT
This specification covers the requirements for UNS C86300, C90500, C91100, C91300, or C93700 bronze alloy castings for turntables, movable bridges, and bridge parts. This specification also includes bronze castings made from the same copper alloys that are suitable for use in bridges and other structures for fixed and expansion bearings in which motion is slow and intermittent. Each product should be manufactured by casting to produce a uniform finished product. Castings made from the UNS C86300 copper alloy should be subjected to Brinell hardness, tension, and compression tests while those made from UNS C91100 and C91300 should be subjected to compression tests. UNS C90500 copper alloy castings should undergo tension tests. All mechanical properties like deformation limit in compression, hardness, and yield strength are determined from separately cast test bars and should conform to the specified requirements.
SCOPE
1.1 This specification establishes requirements for bronze castings for turntables, movable bridges and bridge parts, and bronze castings suitable for use in bridges and other structures for fixed and expansion bearings in which motion is slow and intermittent. The following Copper Alloys are specified: UNS No. C86300, C90500, C91100, C91300, and C93700.Note 1—Historically, the alloys in this specification have been used in the applications listed in Appendix X1. Actual practice may vary.2  
1.2 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 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.
