Aluminum can corrode severely in the presence of other metals. The best example I have seen was my Mercury Zephyr(Ford Faimont). This car had very thick(1/4") aluminum bumpers. I was once hit from behind at a stop light pretty hard with no damage to my car. Yet, after 5 years of ownership those very thick bumpers were corroded right through where the steel mounts were bolted to the fenders
