1.1 This specification establishes the requirements for naval brass rod, bar, and shapes produced from Copper Alloy UNS Nos. C46200, C46400, C46750, C47940, C48200, or C48500.

1.1.1 For piston-finish rod or shafting refer to the Other Requirements Section.

1.1.2 For hot forging material, refer to Specification B124/B124M.

1.2 Units—The values stated in inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. 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 nonconformance with the specification.

1.3 Warning—Mercury is a definite health hazard in use and disposal (see Performance Requirements).

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.


This specification establishes the requirements for rods, bars, and shapes of naval brass with Copper Alloy UNS Nos. C46200, C46400, C47940, C48200, and C48500. Tempers available under this specification are M30 (as-hot extruded), O60 (soft annealed), O50 (light annealed), H60 (cold headed and formed), H02 (½ hard), and H04 (hard). Products shall be tested and shall adhere to dimensional (diameter, shape, length, straightness, and edge contour), mechanical (tensile and yield strength, Rockwell hardness, and elongation), and chemical composition requirements. Products shall also meet piston-finish rod and shafting, and U.S. Government purchase requirements.
