  Lighter... and it melts almost instantly in a fire.  I saw some info on an aluminum air box and one made out of SS. In a fire, the aluminum box melted completely, the SS box held together fine. The box was a hot air diverter for cabin heat. Good demo on why a  heat shield should not be aluminum.  Fire could be from burning fuel or oil, electrical, or an exhaust leak spewing hot gas onto the shield.

    Why wouldn't I use 1/16" aluminum instead of 1/16" stainless steel to cover the fiberfrax on my firewall? It's lighter.
