Abstract

The objective of this investigation was to determine the SCC (stress corrosion cracking) behavior of a commercial Cu-10 Ni alloy CDA 706 in environments other than ammonia, which has been extensively studied by others. For this purpose sodium sulfate solutions of various pHs were chosen. The principal reason for choosing sulfate solutions was that the SO//4** equals ion which was originally thought to be harmless to Cu alloys has recently been shown to be very aggressive, producing severe SCC in the admiralty brass. Beside sodium sulfate solution, some other solutions, Mattsson's solution, sodium nitrate and nitrite were also included in this study.
