Adamantium is a fictional metal alloy in the Template:Marvel Universe. It appears most notably as the substance bonded to the character Wolverine's skeleton and bone claws.


The first use of the term "adamantium" in Marvel Comics was made in Avengers #66 (July 1969) as part of Ultron's outer shell.

However, the noun "adamant" has long been used in standard English to refer to the embodiment of impregnable, diamondlike hardness. It, along with its rhetorical form "adamantine", occurs in works such as the Aeneid, Paradise Lost, Gulliver's Travels, The Adventures of Tom Sawyer, The Lord of the Rings and even the movie Forbidden Planet, all of which predate the use of "Adamantium" in Marvel Comics.

History and properties of adamantium in the Marvel universe[]

In the Marvel universe, Adamantium is a group of man-made metal alloys that possess varying durability but are all almost indestructible. Adamantium was invented by the American metallurgist Dr. Myron MacLain[1] in an attempt to recreate his prior discovery, the properties of Captain America's shield (a unique alloy of steel and vibranium, which required an unknown catalyst for its manufacture); said attempt instead yielded adamantium.[citation needed]

Adamantium's extremely stable molecular structure prevents it from being further molded after its eight-minute initial time period even if the temperature is high enough to keep it in its liquified form. In its solid form, it is colorless, shiny, and resembles high-grade steel or titanium.[2]. It is almost impossible to destroy or fracture in this state and when crafted to a razor edge it can penetrate most lesser materials with minimal application of strength[3]. It is at least somewhat magnetic, since Magneto has manipulated it on multiple occasions[4].

Despite its utility in the creation of armament and/or armature, adamantium is rarely used due to extreme cost, poor reliability and inability to be reshaped. Due to this and the secrecy around the formula few attempts are made to synthesise it[citation needed].

Walter Simonson planned for Apocalypse to be the mastermind behind the Weapon X project that gave Wolverine his adamantium skeleton. Wolverine discovers an adamantium-laced skull in Apocalypse's laboratory and comments how it seemed to have been there for eons.[5]

Types of adamantium[]

Secondary adamantium[]

As true adamantium is extremely difficult and expensive to create or manipulate, some parties found a way to duplicate it on a larger and more cost-effective scale at the expense of quality and durability. For most practical purposes, this secondary adamantium is also largely indestructible. Conventional weapons, such as ballistic missiles, have no effect on it; it is far stronger than even the most durable of titanium or steel compounds. However, extraordinary blunt force, such as a punch from a being with superhuman strength, can warp or break it. Unconventional forms of energy discharges have also been known to warp or damage secondary adamantium, such as Thor's lightning attacks using Mjolnir.[6] Writers created secondary adamantium to deal with supposedly indestructible adamantium having been damaged or destroyed in the past; all such instances were retconned as appearances of secondary adamantium.[citation needed]

Adamantium beta[]

Adamantium beta is a new metal created as a side-effect of the process of bonding true adamantium to Wolverine's bones. His healing factor not only allowed him to survive the process, but also induced a molecular change in the metal. Adamantium beta functions identically to true adamantium, but it does not inhibit the biological processes of bone[7].


Carbonadium is a resilient, unstable metal that is vastly stronger than steel but more malleable and cheaper than adamantium.[8] Due to its malleability, carbonadium is less durable than true adamantium, but still nearly indestructible. Omega Red has carbonadium coils through which he can transmit his ability to drain life energies. Carbonadium is highly radioactive and objects composed of carbonadium have proven to slow the accelerated healing factors of Wolverine[9] and his son Daken,[10] if implanted within the body. While slowed considerably, their healing powers aren't completely suppressed. It is currently unknown if carbonadium affects other beings with superhuman healing powers in a similar manner. The only device that can produce carbonadium, known as the Carbonadium Synthesizer, was initially believed thrown into a river in Brussels by Wolverine; it has since been revealed that the Carbonadium Synthesizer had been hidden on the deceased body of a double-agent who died escaping Omega Red along with Wolverine, Sabretooth and Maverick. The synthesizer was retrieved and handed back to Maverick, whose mission was to retrieve the item for parties unknown.


In X-Men #191, when confronting Wolverine, one of the Children of the Vault named Serafina claims that adamantium has thirteen allotropes, all of which are "unstable, and short-lived, but virulently poisonous". She throws a small device that clamps onto Wolverine's claws and makes them glow green, claiming that it is adamantium nine. This apparently raises adamantium's toxicity dramatically, overloading Wolverine's healing factor.

Adamantium as key component[]

Adamantium is used as the key component in several instances in the Marvel Universe, including:

  • Wolverine's skeleton and claws
  • Agent Zero's combat knife
  • The outer skin of some of Alkhema's robotic bodies
  • Battlestar's shield
  • Bullseye's spinal column and some strips coating several of his bones.
  • Constrictor's original wrist-mounted, prehensile metal coils
  • Cyber's claws and skin
  • A unique set of Doctor Octopus' arms
  • The outer layer of Citizen V's rapier
  • Lady Deathstrike's skeleton and talons
  • One of Mister Fantastic's labs for extremely dangerous experiments
  • Moon Knight's crescent blades
  • A unique suit of armor once used by the villain Stilt-Man
  • The outer skin of TESS-One
  • The outer skin of some of Ultron's robotic bodies
  • One of several layers of containment at the superhuman incarceration facility known as the Vault
  • An outer coating on the Swordsman's blades.
  • A special brand of bullet in the Iron Man suit's ballistic weapons.
  • Underworld uses adamantium bullets
  • X-23's claws
  • Doom 2099 Suit

Durability of adamantium[]

As mentioned above, all forms of adamantium possess extreme durability; however, individuals of sufficient strength can damage it, while unusual energies and forces can destroy it altogether.

Within the Earth-1610 reality, otherwise known as the Ultimate Marvel Universe,[11] adamantium also exists, but there is evidence that brings into question the status of adamantium as "unbreakable" or "indestructible" in comparison with the Earth-616 version. There is an instance of the Hulk breaking a needle made of adamantium.[12] During the initial appearances of the Ultimate Marvel Universe's version of Sabretooth, it is revealed that he has four retractable adamantium claws implanted within each of his forearms. Through circumstances that have yet to be explained, one of the claws implanted within Sabretooth's left forearm is broken.[13] There is also at least one known incident of adamantium within the Earth-1610 reality being damaged by conventional weaponry. In a memory flashback, the Ultimate Marvel version of Nick Fury recalls an adamantium cage containing Wolverine is shelled and destroyed during Operation: Desert Storm.[14]

Properties of adamantium in the Ultimate Marvel universe[]

Little is known about the UMU version of adamantium. Among the most notable information yet to be revealed includes when adamantium is first created, the person or persons responsible for first creating it, and any of the properties and processes used in creating it.

Only one form of adamantium has been seen in the Ultimate Universe thus far. It is currently unknown whether or not any other versions of adamantium exist, as they do in the Earth-616 reality.

Adamantium in the UMU is highly durable and is able to effectively protect a person's mind from telepathic probing or attacks, a property that the Earth-616 version lacks completely. It has been shown as a component of the claws and skeleton of the Ultimate Wolverine and Ultimate Lady Deathstrike. The UMU's version of Sabretooth's natural claws are bonded with adamantium and he possesses four retractable claws similar to those of Wolverine implanted in his forearms. The shield of Ultimate Captain America is composed entirely of adamantium.

Though the UMU version of the Hulk was able to rip Wolverine in half, this was only damage to connective tissue. There was no evidence of damage to any of Wolverine's bones or the adamantium. Although Wolverine himself remarked "unbreakable... so much for that" after being ripped in half.
