Abrégé

An alkaline battery includes a cathode, an alkaline electrolyte, and a copper-based anode which reduces hydrogen gassing without a protective coating or plating to less than 50% of the gas production observed using tin-plated 260 brass. An alloy for a battery anode which reduces hydrogen gassing without a protective coating or plating to less than 50%> of the gas production observed using tin-plated 260 brass includes 0.01% to 9.0% tin, no more than 1% of phosphorus, no more than 1% of incidental elements and impurities, and the balance copper, in wt%. Another alloy for a battery anode which reduces hydrogen gassing without a protective coating or plating to less than 50%> of the gas production observed using tin-plated 260 brass includes 1.0% to 40% zinc, about 0.01% to 5.0% tin, no more than 1% of phosphorus, no more than 1% of incidental elements and impurities, and the balance copper, in wt%.

An antifouling barrier comprising a silicon bronze alloy, the silicon bronze alloy comprising about 0.5% to about 3.8% silicon (wt/wt alloy) and greater than about 90% copper (wt/wt alloy). In some embodiments, the silicon bronze alloy additionally comprises from about 0.05% to about 1.3% manganese (wt/wt alloy). The antifouling barrier may be a welded wire mesh, screen, chain-link, chain-mail, grid, weave, perforated sheet, or chicken wire. Methods of reducing the growth of an organism on an animal enclosure, comprising contacting at least a portion of the animal enclosure with an antifouling barrier comprising a silicon bronze alloy comprising about 0.5% to about 3.8% silicon (wt/wt alloy) and greater than about 90% copper (wt/wt alloy).
