Corrosion Resistance
Good corrosion resistance in drinking-water, brackish water, sea-water (except at high flow rate), salt atmospheres, petroleum products, alcohols. Fairish resistance with respect to acids and alkali. It does not resist in contact with hydroxides, cyanides, oxidizing acids. As a general rule, corrosion resistance decreases as zinc content increases.
