Titanium or TITM should be indestructible and conductive.
It shouldn't melt, shatter, or interact with BOMB or DEST. It could possibly interact with neutrons, but that might mess with it being indestructible if it changes with neutrons.
This would help with creations that need something to conduct like elements, not a wall, and to be able to be made smaller, or into a circle, unlike a wall. It would be helpful for anything that requires a conductor but gets very pressurized or very hot.

You mean like WIRE?I appreciate all these suggestions, but can't a bunch of other popular ideas be easily created too?
Like paper? That could seriously just be wood. I just think it would be nice to have an element specifically coded to be indestructible and conductive.
