Zinc alloy powder for use in an alkaline battery, the alloy consisting essentially of aluminium, bismuth, indium, magnesium, strontium and optionally lead, besides the unavoidable impurities in the aforementioned metals. The alloy can be made by adding pre-alloys of some of the alloying elements or of zinc. The alloy proves useful in reducing the hydrogen gas evolution of the battery.
