Even when the protective zinc coating is broken, the underlying steel is not attacked. Instead, the zinc is corroded because it is less "noble". Only after it has been consumed can rusting of the base metal occur. By contrast, with a conventional tin can, the opposite of a protective effect occurs: because the tin is more noble than the underlying steel, wh… how many calories in a slice of tomatoWebFeb 5, 2009 · In any contact between zinc and aluminum if the aluminum is small relatively to Zinc and in presence of common electrolyte (water or soil) Aluminum will start to corrode.
