Hey there people...

I am curious about the plethora of high temp metals, specifically heat treated and the like. It seems like stainless steel is used a lot, but I see that titanium used for that too. If a person was to want to make a heat shield (example...not specifically a heat shield) what metals are the lightest but yet the most resistant to the affects of high heat. I have seen so many types, with percentages of nickle and other alloys. Anyone have a link to a primer on this?

Thanks in advance...

Titanium is the stuff most commercial aircraft use for a firewall. It is way lighter than any of the stainless steels. It is however hard do do much forming of it though. And expensive.

Sometimes commercially pure Ti is used or if more strength is needed, they use 6Al,4V alloy.

In jet engines there a lot of different kinds of specialty steels used. I would have to ask one of our engine engineers what and where some are used.

That is what little I know.
