Adamantium

Adamantium is a very dense, artificial, iron-based alloy that is virtually indestructible. A sufficient amount is capable of surviving multiple nuclear explosions with no damage. A pure blade of Adamantium is capable of cutting almost any known substance. The ability to slice completely through a substance with an Adamantium blade depends upon the amount of force being exerted and the density of the material in question. Creating even a small amount of Adamantium is astronomically expensive, and only a few people know the complete formula. Adamantium is created by mixing certain chemical resins together. The exact composition of these resins is a closely guarded secret of the United States government. When these resins are mixed and kept at a temperature of 1,500 degrees Fahrenheit, the resulting liquid can be cast or worked into a particular shape. After eight minutes, the mixture sets and becomes solid. Its molecular structure is extremely stable, and its shape can only be altered by precise molecular rearrangement. However, due to the sheer density of Adamantium, there are few known forces capable of altering its molecular structure.
