This study examines the chemical composition of new machinable copper alloys and their susceptibility to stress corrosion cracking, particularly focusing on zinc-containing brass alloys used in contact with potable water. The objective was to assess three newly developed alloy types, which replace lead with other additive elements such as Si, Mg, Bi, and P, and to determine their resistance to corrosion cracking in saline solutions. A slow strain rate test was utilized to evaluate the alloys' performance, alongside a metallographic analysis of the resulting crack formations on test specimens. The findings suggest that while these lead-free alloys maintain good machinability, their resistance to corrosion cracking requires thorough investigation to ensure safety and compliance with future legislation regarding lead in drinking water. The results indicate significant variations in susceptibility, highlighting the necessity for further optimization of alloy compositions to enhance performance in corrosive environments.
