Carbonadium

Carbonadium is a resilient, radioactive metal that is vastly stronger than steel, but more malleable and cheaper than Adamantium. Due to its malleability, carbonadium is less durable than True Adamantium, but still nearly indestructible. The metal was developed in the U.S.S.R.. The technology to create Carbonadium was believed lost in the 1960s.

The coils of Omega Red are made of Carbonadium.
