^A Zinc alloy ingots for die casting may contain nickel, chromium, silicon, and manganese in amounts of up to 0.01, 0.01, 0.01, and 0.01 %, respectively. No harmful effects have ever been noted due to the presence of these elements in up to these concentrations and, therefore, analyses are not required for these elements.

^B The last digit of a UNS number differentiates between alloys of similar composition. UNS designations for ingot and casting versions of an alloy were not assigned in the same sequence for alloys.

^C For purposes of acceptance and rejection, the observed value or cal......
