Has ironman ever made a suit made out of adamantium? If he hasn't why not? I think that a suit made out of adamantium would be great because it is almost unbreakable.

No he hasn't and im not sure if he even has access to that much

Theory: Adamantium would be really hard to modify considering how hard it is to forge after liquidation. It would be nigh impossible to actually modify the suit cause it would be really hard to bend/shape it afterwards if wanting to change it. Another theory is that it is supposedly rare on earth that it is hard to obtain, with adamantium being so rare it might cost a lot of money which starks could afford but also needs to think financial wise if he wants this invincible suit or add ons of more customizable ones. This was wrote on iPad so I apologize if I made errors but this also looked bump worthy.

Doesn't Tony usually just build entirely new suits, rather than modify new ones? And, besides, his suits are made of numerous components. It's not like it's one, big, solid piece. He can easily replace any part with a new one, should he choose to modify the suit.

@maddpanda531: I made a lot of errors but I can't dispatch what I said so you can disregard it.

To wear adamantium as a fully flexible suit requires that you constantly change it's molecules, something Ultron and Magneto can do, it may simply not be possible for him at the moment.

Adamantium is to unbendy. They use to use Carbondonium (I think thats what its called) Which was as strong as Adamantium but easier to move as armor

But they Learned it poisoned people.
