Abstract
Abstract An electrochemically active aluminum alloy characterized in that it consists essentially of, per 100 parts of weight of aluminum, 0.01-1 parts of weight of gallium and/or indium and in that it consists essentially of 0.01-1 parts of weight of phosphorous. The alloy is prepared by simultaneous fusion of the components in an inert atmosphere, or by a previous fusion of aluminum, gallium and/or indium to which phosphorous is then added in an inert atmosphere. Examples of use of the alloy include battery anodes and anti-corrosion coatings.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
39 words
Electrochemically active aluminum alloy, characterized in that it consists essentially of, per 100 parts of weight of AL, 0.01-1 parts of weight of Ga and/or In, and in that it consists essentially of 0.01-1 parts of weight of P.
Claim 2
Dependent Claim
39 words
Electrochemically active aluminum alloy, characterized in that it consists essentially of, per 100 parts of weight of AL, 0.01-1 parts of weight of Ga and/or In, and in that it consists essentially of 0.01-1 parts of weight of P.
Claim 3
Dependent Claim
54 words
Electrochemically active aluminum alloy as in claim 1, characterised in that it is prepared by simultaneous fusion of the components in an inert atmosphere, or by a previous fusion of Al, Ga, and/or In, to which P is then added in an inert atmosphere, the obtained melted mixture being then submitted to quick cooling.
Claim 4
Dependent Claim
26 words
Electrochemically active aluminum alloy as in claim 2, wherein the melted mixture is submitted to quick cooling by pouring the mixture into a cold metallic mold.
Claim 5
Dependent Claim
21 words
An anode for use in chemical sources of electrical current formed from the electrochemically active aluminum alloy defined in claim 1.
Claim 6
Dependent Claim
18 words
An article provided with an anti-corrosion protective coating of the electrochemically active aluminum alloy defined in claim 1.
