Ya, my company makes intake and exhaust parts for jet engines out of this material. Very expensive. Used in extremely high heat, applications. It is also heavy, not sure the exactly how it compares to Stainless steel, but they are very very similar, inco possibly tipping the scales slightly on SS. As for forming and fabrication, Inconel is difficult to work with, but not too bad, thats my bread and butter
. It would be a great choice for turbo components or headers, but even then, Stainless steel is sufficient for a street car. I am very curious what would cause a company to dive into using such an alloy, aside of course form the "bling" factor, which would be a minimun due to the fact that 90% of the public has no idea what inconel is.
That being said, I can definately appreciate the product and look forward to seeing some numbers.
