Abstract

The alloys contain, besides zinc and unavoidable impurities, PA0 0.05-0.8% of Pb and PA0 either 0.005.1% of Al and 0.0005-0.1% REM, REM being a rare earth metal or a mixture of rare earth metals, or PA0 0.005-1% of Mn or PA0 0.005-1.5% of a mixture of Al, REM and Mn. These alloys have a higher mechanical strength and a better resistance to corrosion than the known alloys with Pb-Cd or Pb.
