    C14500 copper-tellurium
    C14700 copper-sulfur
    C36500 leaded Muntz metal
    C37000 free-cutting Muntz metal
    C37700 forging brass
    C46400 naval brass
    C48200 medium leaded naval brass
    C48500 leaded naval brass
    C61900 aluminum bronze
    C62300 aluminum bronze, 9 %
    C63000 aluminum-nickel bronze
    C63200 aluminum-nickel bronze
    C64200 aluminum-silicon bronze
    C64210 aluminum-silicon bronze, 6.7 %
    C65500 high-silicon bronze (A)
    C67500 manganese bronze (A)
    C67600 . . .
    C69300 copper-zinc-silicon
    C70620 copper-nickel 90-10
    C71520 copper-nickel 70-30
    C77400 nickel silver, 45-10

    1.2 UnitsThe values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    Note 1—Nominal composition and relative forgeability ratings are given in Appendix X1. Copper-nickel alloys C70620 and C71520 are intended for welded applications with seawater exposure.

    Note 2—Wrought product intended for hot forging is described in Specification B 124/B 124M.

    1.3 The following safety caveat pertains only to Section 10 of this specification. 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.
