Active Standard ASTM B981 / B981M | Developed by Subcommittee: B05.02
Book of Standards Volume: 02.01
This specification establishes the requirements for low leaded brass rod, bar, wire, and shapes of any specified cross section produced from Copper Alloys UNS No. C36300, C36500, C37000, C37100 and C37700 suitable for high-speed screw machining applications. It covers tensile and chemical requirements, as well as temper, dimensions, mass, and permissible variations. The material shall be tested by chemical analysis, and chemical composition shall, in case of disagreement, be determined subject to agreement between the manufacturer and the purchaser.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification establishes the requirements for low leaded brass rod, bar, wire, and shapes of any specified cross section produced from Copper Alloys UNS No. C36300, C36500, C37000, C37100 and C37700 suitable for high-speed screw machining applications.
Note 1—Refer to Specification B124/B124M when purchasing bar or rod for forging production.
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.
