In order for the firewall to be true to it's name I am assuming that all stainless steel firewalls are constructed using steel fasteners and steel stiffeners, if any. If we had a firewall that was attached and stiffened with aluminum, then in a fire, these supporting aluminum members would fail long before the steel sheet itself, essentially causing the firewall assembly to fail. The problem I see right now is that suppliers like Aircraft Spruce does not sell steel rivets, so I'm thinking, do people use aluminum rivets in their firewalls?
