摘要
Magnesium-aluminum corrosion-resistant alloys are provided and include magnesium, aluminum, germanium, small amounts of cathodic reaction active site impurities such as iron, copper, nickel, and cobalt, manganese, and optionally tin. The alloy can include up to about 0.75% germanium, at least about 2.5% aluminum, up to about 2.25% tin, at most 0.0055% iron impurities, and at most 0.125% silicon impurities. The ratio of germanium to iron can be less than 150. The ratio of manganese to iron can be at least 75. The alloy can comprise one or more intermetallic complexes, including magnesium-germanium, magnesium-aluminum, and aluminum-manganese internietallic complexes.
