This specification establishes the requirements leaded brass plates, sheets, strips, and rolled bars made from UNS C33500, C34000, C34200, C34000, C35000, C35300, or C35600 copper-zinc-lead alloys. Each product should be manufactured by hot or cold working, and annealed if required, to produce a uniform wrought structure that meets the specified temper properties. This specification also contains information on the standard tempers of rolled and annealed materials as well as the required tensile strength, Rockwell hardness, and grain sizes. The Rockwell hardness test can be used to test for general conformity to the specification requirements for temper, tensile strength and grain size.

1.2 Units—Values stated in either 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 non-conformance with the standard.
