Popis:	The effects of individual additions of from 0 to 0.04 pet Pb and Sn on the corrosion resistance of sand cast Zn-12 pet Al alloy in saturated water vapor at 95°C were investigated to establish limits for these impurities and thus the feasibility of using secondary Zn to make this alloy. The effects of Cu (0.5, 1.0, and 2.0 pet) and Mg (0.02, 0.05, and 0.1 pet) on corrosion resistance were also studied and the optimum combination for tolerance to Pb and Sn was found to be 1.0 pet Cu and 0.02 pet Mg. In this alloy up to ∼0.01 pet Pb could be allowed. The harmful effect of Sn was much greater than that of Pb and was not progressive but showed a maximum at 0.0025 to 0.005 pet and a second minimum at 0.01 to 0.02 pet. The safest limit for Sn is considered to be ∼0.001 pet.
