  • Copper Corrosion - an overview

    Zaki Ahmad, in Principles of Corrosion Engineering and Corrosion Control, 2006. 2) Galvanic Corrosion The potential range of aluminum alloy lies between –0.6 and 0.8 V vs the saturated calomel electrode. If aluminum is connected to copper (corrosion potential = –0.1 V), a significant difference of potential (–0.5 V) would exist and aluminum, being anodic to copper, would corrode.
