Fictional history and properties

The components of Adamantium are kept in separate batches before molding. Adamantium is prepared by melting the blocks together, mixing the components while the resin evaporates. Adamantium has a stable molecular structure that prevents it from being further molded even if the temperature is high enough to keep it in its liquefied form. In its solid form, adamantium is near-impossible to destroy or fracture, and when molded to a sharp edge, can penetrate most lesser materials with minimal force. Adamantium is used in

Other versions

Secondary adamantium

Marvel's comic books introduced a variant of "true" adamantium, "secondary adamantium", to explain why in certain stories adamantium was shown to be damaged by sufficiently powerful forces. Its resilience is described as far below that of "true" adamantium.

Ultimate Marvel

In the Ultimate Marvel imprint, adamantium possesses the additional ability to protect against telepathic probing or attacks. Unlike its main universe counterpart, adamantium is not depicted as indestructible.

Comparison with real materials

Scientist David Evans argued that as adamantium "is considered to be a very dense and indestructible metal" the most suitable real material to model it would be osmium, "the densest known metallic element".
