ABSTRACT:
Aluminum base alloys are disclosed which contain up to 2.0% by weight zinc, up to 5.0% by weight magnesium, less than 0.1% by weight iron, elements selected from the group consisting of cadmium, tin and lead, or any combination thereof, in amounts ranging from 0.05 to 0.3% by weight for each of cadmium and tin and from 0.01 to 0.15% by weight for lead, balance aluminum. These aluminum base alloys are particularly useful as anode material for primary electric cells. The aluminum alloys reduce the incidence of hydrogen gas evolution within the cells. The aluminum base alloys may also be utilized as anode material for uses other than primary cells.
