1.1 ,This specification covers aluminum–,base and zinc–,base master alloys used to make zinc die-casting alloys. Alloy compositions specified for aluminum–,base master alloys (hardeners) are designated as shown in Table 1. Alloy compositions specified for the zinc-base master alloys are designated as shown in Table 2.
(A) ,Carried to one additional decimal place to ensure proper control in the final alloy.
