  • Electrochemically active aluminum alloy and composite
    Patent number: 4288500
    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.

  • Electrochemically active aluminium alloy, the method of its preparation and use
    Patent number: 4098606
    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.
