Adamantium can be used as a manufacturing material. It has the following properties:
- Extreme tensile and compressive strength.
- Extreme heat resistance.
- Extreme density.
Adamantium, also known as hellsteel or neutronium, is a reddish supermetal, the result of processing extremely rare adamantite, which is mostly Tungsten and Osmium by mass, plus unidentified elements. The material presents an enormous density of 24 g/cm3, an extreme resistance to physical deformation or fracture, and is pyrophoric. As such, it is primarily a perfect material for armour-piercing projectiles, and can take advantage of much higher pressure loads (for example, from cartridges using firedust instead of smokeless powder) to transfer far more kinetic energy. A 7.62x51mm NATO adamantium bullet propelled by firedust has about half as much kinetic energy as a .50 BMG shot, almost triple as much as a standard round of its calibre.
