The strongest materials in the Marvel universe are Vibranium and Adamantium. In the Star Wars universe there is Cortosis, with a special resistance against energy weapons like blasters and lightsabers. There is Unobtainium light, strong at high temperatures, and resistant to radiation damage.

What is the strongest material in DC?

    Cortosis isn't indestructible, and is described as being relatively brittle, but has a special resistance against energy weapons like blasters and lightsabers. Feb 12, 2017 at 2:32

I did some checking, and I came up with a few possibilities.


The first one I found is called Inertron, which is described on Wikipedia as the "the hardest, densest substance in the DC universe."


Another choice would be "Supermanium", which is apparently the substance used to craft Superman's Supermobile aircraft. It apparently is vulnerable only to one of Superman's power.

a metal so strong that "only Superman's heat vision can soften the substance, and only his super-strength is mighty enough to mold it!"

Nth Metal

Finally, there is Nth metal, a magical metal used by Hawkgirl and Hawkman. It's not clear how physically durable/resistant the metal is, but it does imbue the wearer with tremendous powers. It seems reasonable to assume that it is an extremely strong substance as well.

    Inertron is also the least mobile of the Transformers

    I thought the hardest, densest material in the DC universe was Guy Gardener's skull... Feb 12, 2017 at 16:22

    More correctly, Supermanium is the material used to build the Supermobile - Superman "powers" the craft himself. It's essentially a ship-shaped suit of armor that is proof to red sun radiation and Kryptonite. While Inertron is highly study, it is not completely indestructible - Matter-Eater Lad can eat it, and Karate Kid has been able to break it. Feb 14, 2017 at 15:59

Promethium, in its depleted form, forms a nearly indestructible metal when alloyed with titanium and vanadium. The pre-Rebirth Cyborg (Victor Stone)'s robot parts were made of depleted Promethium alloy. That may no longer me the case now - his armor now contains Apokoliptian / Mother Box technology that may even exceed that metal's strength.


Superman (in World's Finest #41) creates a new element by applying heat and pressure to an ore. It's named Supermanium in his honour and is described as 'the hardest substance in existence'.

enter image description here

This is backed up in Superman #167, where it's described by Brainiac (who's pretty smart) as 'the strongest metal known to science'.

Interestingly, in Superman #365, Superman himself describes it as the 'densest' metal known, so it's apparently both the densest and strongest.

Honourable mention #1 goes to Amazonium, also described by Diana (in Wonder Woman #52) as the 'hardest metal known'.

and by the narrator in similarly glowing terms in Wonder Woman #68.

enter image description here

Honourable mention #2 goes to Marvelium, created by Captain Marvel in Captain Marvel Adventures #100. Much like Supermanium, it's created by crushing other elements to make the 'heaviest and strongest element of all'.

enter image description here

Honourable(ish) mention #3 goes to Inertron, a metal created by Brainiac 5 in Adventure Comics #336 that is supposedly "the most indestructible substance in the galaxy". It loses points because it gets destructed repeatedly, by Karate Kid, Superboy, Element Lad, Mon-El and various others over the next few decades.
