Cover Story: This study presents the first standardized corrosion analysis of the zinc-based wrought alloy ZnAl15Cu1Mg (ZEP1510) as a lead-free alternative to CuZn40Pb2 and galvanized steel. Using salt spray tests (DIN EN ISO 9227), climate chamber exposure (DIN EN ISO 6270-2), and electrochemical potential measurements in NaCl and Na2SO4 electrolytes, ZEP1510 showed corrosion resistance comparable to brass and significantly superior to galvanized steel. ZEP1510 maintained structural integrity and exhibited stable passivation behavior under both neutral and humid conditions, highlighting its potential for sustainable industrial applications in sanitary, automotive, and electrical engineering. View this paper
