    I would probably lean towards the softer metals. Stainless would be nice as most is soft and rust/corrosion would be no problem. The key essentially locates the flywheel on the crank. Tightening it on the taper is what keeps it there. If you don’t feel good about the taper you can lap it in with valve grinding compound. That’s what we have had to do even on big V-6 engines!
