I was told that inconel is what was used in jet engines to take the heat. It was the only thing that would take the heat and not crack. I hope thats correct, cause I reached real deep in my pockets to insure I was doing the right thing for my application. Gonna be a real pisser if it cracks! Expecially if I go down in flames!

Lynn, have you tried anything build with incoel

Bob Mears

Nope.

I have two sets of Indy Car headers in Inconel. Very thin works of art. They are discarded after three heat cycles, because they crack.

I have never tried to make anything in Inconel, although I have a TIG machine.

Lynn,

That confirms what I have read about Inconel - it's light ( for racing), it's very expensive, it takes heat very well and all that's good for both racing types and those with deep pockets. Wait for it, there's more - it doesn't last. That's OK for racing but not good for Aviation!
