ASTM B275-14 - 1.10.2014
 
1. Scope

1.1 This practice covers a system for designating die casting alloys of zinc, tin and lead. Those designations currently being used in specifications under the jurisdiction of Committees B02 on Nonferrous Metals are listed in  Table X2.1 in Appendix X2.

Note 1: The alloy designations now being used in Committee B07 specifications for aluminum and aluminum-alloy wrought and cast products conform to ANSI H35.1. Alloys formerly codified by this practice and the corresponding ANSI designations are shown in Tables X3.1 and X3.2 of Appendix X3 for legacy purposes.

Note 2: The alloy designations now being used in Committee B07 specifications for magnesium and magnesium-alloy wrought and cast products conform to Practice B951, as indicated in Appendix X4. Alloy designations formerly codified by this practice are no longer relevant.

1.2 The equivalent Unified Numbering System (UNS) alloy designations shown in the appendixes are in accordance with Practice E527.
