What Is Thor’s Hammer Made Of?

For all you marvel fans out there, you will know that Mjolnir is the trusted hammer of Thor.

This hammer has accompanied Thor in his adventures from the very start, first as a guest in other people’s comics, and later in Thor’s own comic series. Whatever Thor has appeared in, so has Mjolnir.

In the Marvel comics, Thor’s hammer Mjolnir is constructed of the fictional metal Uru. Uru is also the best metal if you want the hammer to store magic as well. The only place where Uru can be acquired is in Asgard, home of the gods.

What Is Thor’s Hammer Made Of

The Famous Hammer Was Not Created In A Normal Forge

Over the years, there have been many stories about how Mjolnir originated. The most recent story in the comics is also used in the MCU ( Marvel Cinematic Universe ). The Thor movies tell people that Mjolnir was forged in the heart of a dying star. 

Those that were concerned with forging the hammer were Eitri, Brok and Buri who were following Odin’s instructions to construct a superweapon for Asgard.

To achieve this, the three blacksmiths summoned up a forge in the middle of a dying star where they forged Mjolnir out of the Uru metal, gathered from Asgard.

The metal used for the hammer, which is unique to Asgard, is in the same strength levels as Adamantium.

Mjolnir Took Out The Dinosaurs 

To create a weapon like Mjolnir, it is not a tranquil process. 

In fact, the explosion caused by the construction of the hammer was so powerful that it was responsible for the mass extinction of dinosaurs on Earth. The force of the blast was so strong that it could have even destroyed Earth entirely.

Beware Of Imitations Of The Hammer

Due to the power of Thor’s hammer, there have been many attempts to replicate it over the years. However, none of them have been successful and none of these copies have had the unique power of the Mjolnir.

Does The Hammer Have The Power To Bring Back The Dead?

The civil war comics arc was a long storyline which is eclipsed with Captain America being shot and killed. 

Later on, within another comic, they decided they wanted Captain America back so it was announced that anyone who has sworn an oath over the hammer (which Captain America had) could be brought back from the dead.

Thor then chose to use this new ability to call Captain America back, so that he could say goodbye.

You Have To Be Deemed Worthy To Carry Mjolnir 

As Thor’s hammer has magic. This means that only the most worthy can lift the hammer and take advantage of the power it provides.  Other people who try to use the hammer will not be able to make it budge.

The story of the Mjolnir is very similar to that of the Excalibur where only Arthur is worthy enough to lift the sword from the stone.

Over the years in comics, there have been a couple of ties where Thor has been judged unworthy to use the Mjolnir. The first of these occasions was when Odin banished Thor to Earth.

It then happened on a second occasion where there was an incident with Nick Fury, resulting in Jane Foster taking over the famous hammer. Jane Foster was Thor’s big love interest in other stories and the MCU.

Other Characters That Have Lifted The Hammer

This list only features people who have lifted the genuine Mjolnir and not those who have lifted fakes. However, this list does not include those who have found a loophole, which is a way around the magic.

Awesome Andy

The first character on this list got around the problem because he was not human. The magic states that no other human who is not worthy can lift the hammer. The case with Awesome Andy, who appeared in She-Hulk, was recast as an amiable legal assistant in the offices of Goodman and Lieber.

It is apparent that the “Mad Thinker” had given Andy (who was an android) the ability to mimic other human beings. Andy was able to copy Thor’s nobility and thereby lift the hammer. That is the reason that he is working in the legal office, in order to pay off his legal bills. 

Beta Ray Bill

Beta Ray Bill was the protector of the Korbonites and he had been genetically improved to suit this role. In terms of the hammer, due to a little mix up between him and Thor, Beta Ray Bill managed to knock Thor unconscious, and Thor changed back to the form of Dr. Donald Blake. 

For some reason, Bill decided to pick up Dr. Blakes’s walking stick and bash it against the wall. As he did so, he suddenly found himself holding Mjolnir. 


When Mjolnir was first created on the orders of Odin, Odin also had the capability to carry the hammer. Later on, Loki, who at the time was a woman in Thor 600, decided to resurrect Odin’s father.

This did not end up going to plan and Bor, who is Odin’s father, decided that Manhattan was a realm full of demons (he had a point) and started smiting people. Thor then had to intervene and the two fought during which Bor grabbed Mjolnir and held it for a moment before tossing it aside.

Captain America

If you take time to think about it, Captain America can’t be any less worthy than Thor yo hold Mjolnir, and that is how Captain America has managed to hold Mjolnir not just once but twice.

  1. In 1998, Captain America was doing a bit on the side as plain Captain and he came to visit his chums at the mansion. Thor was a part of these chums. As part of this visit, Grog and the Demons of Death attack, and for a moment or two Thor was pinned down out of reach of the Mjonlnir. Eventually, Captain America managed to reach the hammer and toss it to Thor.
  2. During “Fear itself” Captain America had his shield broken by the Serpent and was severely lacking in weapons to attack the Serpent. Thor, who was battling his uncle, then dropped the Mjolnir which landed in Captain America’s lap which proved quite useful for the attack on the serpent.

Final Thoughts

To conclude, that is the story of Mjonlnir!  As you can see from this article, it is a pretty formidable weapon and without it, Thor is nowhere near such a deadly opponent.
