ASTM B16/B16M-10(2015)
(Specification)Standard Specification for Free-Cutting Brass Rod, Bar and Shapes for Use in Screw Machines
Standard Specification for Free-Cutting Brass Rod, Bar and Shapes for Use in Screw Machines
ABSTRACT
This specification establishes the requirements for free-cutting brass rod, bar, wire, and shapes of any specified cross-section produced from Copper Alloy UNS No. C36000 suitable for high-speed screw machining applications and moderate thread rolling. The chemical composition, temper, tensile, Rockwell hardness, and shape requirements are detailed.
SCOPE
1.1 This specification establishes the requirements for free-cutting brass rod, bar, wire, and shapes of any specified cross section produced from Copper Alloy UNS Nos. C36000 or C36010 suitable for high-speed screw machining applications and moderate thread rolling.
1.2 Units—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.
1.2.1 Within the text, SI units are shown in brackets.
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
