• Zinc-aluminum ingot for foundry and pressure die casting may contain chrome, manganese, or nickel in amounts of up to 0.01 % each or 0.03 % total. 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.
