If you want something lighter....

I'd suggest 6AL-4V alloy Titanium.

It has a thermal conductivity of 7.5 vs 13 (316 SS), and has a 400+F higher melting point.

Density is .16lb/cu in. vs .285 for SS, approx 56% lighter.

It's just as easy to work with as SS, and doesn't work harden.

It does cost a bit more  - I paid $90 more for Ti vs SS.

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