Abstract
This specification establishes the requirements for free-cutting a bismuth brass rod, bar and wire of UNS Alloy No.C49250 and C49260 suitable for high-speed screw machine work or for general applications. Typically, products made to this specification are furnished as straight lengths or coils when requested. The material shall conform to the chemical composition requirements, tensile strength requirements, and elongation requirements stated in this specification.
Scope
1.1 This specification establishes the requirements for free-cutting bismuth brass rod, bar and wire of UNS Alloy No. C49250 and C49260 suitable for high-speed screw machine work, or for general applications.
1.2 Typically, product made to this specification is furnished as straight lengths, or coils when requested.
1.3 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.
1.4 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.
