Abstract The intermetallic phase Mg 2 Al 3 was synthesised in bulk form to permit electrochemical characterisation. Polarisation testing was performed in 0.01 M NaCl across the pH range of 2–10, which is relevant to instances where the Mg 2 Al 3 phase populates Al-alloys (i.e. 5xxx series). Mg 2 Al 3 is capable of sustaining high dissolution rates, but this is pH dependent. As such, the range of currents sustained over the E-pH space are reported and are of general use for reconciling localised corrosion or corrosion model feedstock in other works.
