ABSTRACT:
An alloy composition comprises lead, tin and zinc, each being present in an amount of between about 20 and about 45% by weight. Preferably, the composition also contains small amounts of up to about 0.1% each of copper and tellurium. When in contact with water or other aqueous composition, the alloy generates a current directly proportional to the alloy surface area exposed to the liquid.
