Abstract
An aluminum alloy contains at least about 0.01 to 0.2 weight percent gallium, at least about 0.01 to 0.2 weight percent tin, and at least about 0.01 to 0.2 weight percent lead. In another embodiment, the alloy may contain at least about 0.01 to 0.2 weight percent indium in lieu of the tin. The balance of both alloys is aluminum, tolerable levels of trace metals, and impurities. Preferably, the aluminum is present in 99.9% purity. The alloy can be used advantageously as an anode in an aluminum-air battery. The gallium-tin-lead aluminum alloy when used as an anode, is preferably used with a salt water electrolyte. The gallium-indium-lead alloy, when used as an anode is preferably used with a caustic electrolyte. The aluminum base alloy may be used as an anode in a battery assembly, a housing, an anode of the present invention, a cathode, and a support means within the housing to secure the anode and cathode in a relative spaced relationship.
