OK... I'll bite. Why does it conduct if there is an insulating coating of Alox on the surface?? Does this give me a clue? https://www.researchgate.net/post/What_is_aluminium_and_its_oxide_electrical_properties2 It mentions tunneling. Sounds like a semi conductor property. Next question; Why do aluminum electrical connections tend to melt down sometimes?? I've experienced several aluminum wire to terminal failures... However most of them were made without the mandatory anti-corrosive paste.
