Abstract
High‐purity aluminum has nearly perfect galvanic compatibility with magnesium AZ31B alloy during saline exposure. This compatibility is little changed by additions to the aluminum of magnesium, silicon, or manganese, but it is rapidly and proportionately decreased by the addition of iron, copper, and nickel, and more gradually decreased by the addition of zinc. The addition of magnesium to the alloy or magnesium ion to the environment can greatly suppress the effect of the above deleterious constituents.Keywords
