Stress corrosion behavior of alpha Al bronze (Cu-7 percent Al) (UNS C61400) was studied in solutions of 0.1 M to 8 M sodium hydroxide (NaOH) under various potentials (600 mV vs normal hydrogen electrode (NHE) to 800 mV_(NHE)) and slow strain rates. Analysis of the results of time-to failure (t_f), maximum yield stress (#sigma#_(max)), and the morphology of the fracture surface indicates that the alloy resists stress corrosion cracking (SCC) under all test conditions, including those where the alloy undergoes selective dissolution. The susceptibility (S) to SCC in the above tests was <= 14 percent where S combines the ratios of t_f and #sigma#_(max) under the test and in air.
