PURPOSE:To obtain the zinc alloy for a battery electrode having less generation of hydrogen gas and having good discharging battery capacity by adding specified amounts of Ga, In, Pb and Al to high purity zinc in which the contents of Ni, Cr, Mo, Sn, Sb and Fe are regulated. CONSTITUTION:High purity zinc of, by weight, >=99.995% zinc purity constituted of each <=1ppm Ni, Cr, Mo, Sn and Sb is incorporated with 0.001 to 0.01% Ga, 0.01 to 0.05% In, 0.01 to 0.1% Pb and 0.01 to 0.06% Al, according to necessary, which is mercurated into <=1.0% Hg concn. to obtain the zinc alloy for an alkaline battery electrode. The zinc alloy has less generation rate of hydrogen gas at the time of storing and less dispersion thereof in the state of low concn. mercuration or unmercuration, furthermore has good discharging battery capacity and can stably be obtd. at low production cost. |
