Abstract

Abstract An electrochemically active alloy of aluminum with indium, gallium and thallium, in which the alloy would consist of, by weight percentage, about 0.01% to 0.5% of indium, gallium, or thallium of varying and selective composition, while the ratios between indium, gallium and thallium are arbitrary. The method would incorporate heating a selected composition in an inert atmosphere to melting and subsequent cooling.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 41 words
The electrochemically active alloy of aluminum in which the alloy consists of, by weight percentage, from 0.01% to 0.5% of gallium, from 0.01% to 0.5% of indium and 0.01% to 0.5% of thallium, with the balance being aluminum with incidental impurities.
Claim 2
Dependent Claim 41 words
The electrochemically active alloy of aluminum in which the alloy consists of, by weight percentage, from 0.01% to 0.5% of gallium, from 0.01% to 0.5% of indium and 0.01% to 0.5% of thallium, with the balance being aluminum with incidental impurities.
Claim 3
Dependent Claim 65 words
A method of obtaining an electrochemically active alloy of aluminum as claimed in claim 1, the steps comprising heating a composition in an inert atmosphere to melting, homogenizing the melt by mixing and cooling, the composition consisting of, by weight percentage, 0.01% to 0.5% of indium, 0.01% to 0.5% of gallium, and 0.01% to 0.5% of thallium, with the balance being aluminum with incidental impurities.
Claim 4
Dependent Claim 43 words
A method of obtaining an electrochemically active alloy of aluminum as claimed in claim 2, in which the cooled alloy is reheated to between 300° C. to 400° C. for about one hour to four hours and subsequently slowly cooled at ambient temperatures.
