High strength aluminum alloys have been successfully used to construct aircraft, bridges, deep diving submarines, surface ships and a host of other critically designed structures which utilize the high strength-to-weight ratio inherent in these alloys. These applications have been possible because designers and engineers have been aware of the characteristics of these alloys, for the most part. In remarkably few cases, considering the widespread usage, have problems arisen due to susceptibility to stress corrosion cracking. When a problem comes up, it is usually due to the fact that one of the three principles in avoiding such trouble has been overlooked.
