Intake manifolds are not steel anymore. Most are plastic, actually. Exhaust manifolds are iron, steel or stainless steel.
I love these melt temps scenarios presented. These cars are outside, not in an oven. Wind etc. You'd need a complete "bubble" at those temps to liquify. Like a kiln so-to-speak.
I've seen a few car fires in my day. Racing, on the road etc. Never complete aluminum liquification on long burns. Ever.

Correction. I confused intake manifold with exhaust manifold.
Just because you didn't see it, doesn't mean it doesn't happen. Archive footage of car fires shows aluminum pools in many cases.
