Does adamantium metal really exist?
Adamantium is just a fictional metal created by Stan Lee in his comic book, "X-Men".
It is too cost-worthy to try manufacturing proper Adamantium, so scientists manufactured a duplicate to Adamantium called Secondary Adamantium (surprise surprise), which Ballistic Rockets have no effect on. It is nearly Indestructible, but, as I said, COST-WORTHY
Wolverine was born a mutant with a healing abillity and bone claws which could come out his knuckles. Later in life he was experimented on by wepon x, where he undergoed a prosiduer in which the unbreakable metal adamantium was covered over his skeleton, which he survived with his healing and made his bone claws covered in adamantium from then on.
if it exist yes, but unless you possess some kind of regeneration or healing factor, the injection/bonding process will kill you as the only way to inject Adamantium is by injecting it in its raw liquid form (which is very hot) and human body will died from the injecting process as injecting raw boiling liquid metal to human will effectively fry them alive. Even if you possess some kind of healing factor, this process can…
He was born with bone claws that he can make emerge from his hands and retract back in. It's just one of the things that makes him a mutant. Later on in his life, he is kidnapped by Weapon X where he was experimented on and was forced to have adamantium fused to his bones. So his entire skeleton is now made of the metal, therefore his claws that were originally bone, are now adamantium.
How do the Adamantium bullets work in X-Men Origins Wolverine and what happens to them at the end of the movie?
There is no acceptable explanation in current physics on how those bullets work in the movie, because of two reasons: 1 - How adamantium works in the Marvel Universe: Adamantium is a fictional man-made metal alloy that has been frequently described as being virtually indestructible* 2 - How force works: To every action there is an equal and opposite reaction. To penetrate a virtually indestructible material utilizing bullets it would require them to be propelled…
Wolverine is stronger than Saber tooth, because his body is made out of special metal called Adamantium which he would be really hard to beat, so technically wolverine is invincible, Saber tooth isn't. And he is only immortal for age not for health. And wolverine could kill him, but it's difficult to catch Saber tooth.
Adamantium is expensive and notoriously difficult to produce. If Stark could get his hands on enough to produce a suit, he would have to keep the metal at a super-heated liquid state until he is ready to make the suit. If for some reason the metal cools before it is set into it's mold, it would be useless. The metal is nearly impossible to melt down or break once it is in a hardened state…
