... improper selection of the braze alloy for the service environment. In most cases, uniform corrosion occurs when the braze alloy is exposed to environments in which it has inherently low corrosion resistance. Stainless steel parts are widely brazed using copper as a braze alloy under vacuum, dissociated...
