A compilation of corrosion potentials reported for Al‐based intermetallic compounds is presented. The range of corrosion potentials for dilute aluminum binary alloys is also given. This compilation is intended to serve as an aid in establishing galvanic relationships among discrete microstructural elements in aluminum alloys. This compilation is based primarily on data reported in the corrosion literature with a focus on corrosion potentials for intermetallic compound particles found in commercial alloys.
