Aluminium is vulnerable to corrosion. If you have bought an A/C one inspection is for this very thing. Aluminum in the presence of salts or dissimilar metals will degrade. It is unlawful to wire a home with it and furthermore, Wiki as a source is bollocks. What it does do is protect itself by oxidation of its outside layer, scratch that off at a terminal and corrosion begins, I can't believe AI used Aluminum cabling.
