unobtainium 

Term used by engineers and hobbyists to define a material that is extremely hard to obtain.

-Space rockets are mostly made of unobtainium.
-There are so many conflicts in Africa due to the presence of unobtainium in the ground.
-Your CNC machine will crash only when you machine this one piece of unobtainium. Of course, you do not have enough to make a new piece.

A piece of shitanium that got broken will magically turn into unobtainium if you look for a replacement (Thus making it extremely expensive, even if you found one)
