Adamantine

Adamantine (or adamantium) is a type of metal.

Adamantine steel chains were used in Grim Batol to hold the Dragon Queen Alexstrasza chained.

Goblins created the adamantine steel plates that drogbar slaves adhered to Deathwing's body to hold it together.

In the RPG
It is an ultra-hard metal that adds to the quality of a weapon or suit of armor. Weapons fashioned from adamantine have a natural ability to bypass hardness when sundering weapons or attacking objects. Only weapons, armor, and shields normally made of metal can be fashioned from adamantine; an arrow (the arrowhead) can be made of adamantine, but a quarterstaff cannot.
