Short version of what he said (he said a lot), was no aluminum. Basically through the heat cycles and temp range, it'll loose it's properties and is at risk of failure.

He mentioned aluminum calipers can work due to them being cast(explained the structure of the metal etc.. went beyond what I needed to know :P) and specific alloys being used/chosen combined with cooling techniques employed in car design etc.

Anyways, his first choice was Inconel.. But I said our budgets won't allow it :P

He then said, just choose a common SS and it'll work.


Like Halon mentioned, welding is a whole new world after being directly involved in it for about a year. Not machine welding, human welding. There is a ridiculous other world of AWS/ASME codes/practices etc that need to be strictly followed in the Nuclear world.
