Abstract: A tin and mercury free aluminum alloy of specific composition for use as an node in fuel cells and electrochemical couples and particularly in a silver oxide-aluminum battery comprising high purity aluminum alloyed with gallium and magnesium in specified quantities. The aluminum in combination with the gallium provide desired unique electrochemical properties. The magnesium, when the anode material is suitably heat treated, increases the tensile modulus of the alloy.
