The maximum temperature of Superman's heat vision is 5000C. It probably couldn't burn through vibranium. But you can heat the metal to a soft red point, and it can also be melted. So Superman could melt vibranium with his heat vision.
Superman can break Vibranium, but he can't break Adamantium. The Hulk holds a planet together, so in physical strength he is similar to Superman's, and the Hulk can't melt adamatium, plus the sun can't melt this metal either, so we have no evidence that Superman's heat vision can do the job.
In Age of Ultron, concentrated energy blasts of sufficient heat and power are also shown to be effective against Vibranium. Thor's lightning, Vision's Mind Stone lasers and Iron Man's repulsor beams were able to melt Ultron's body when used in combination, meaning that high enough temperatures can break Vibranium down.
Further, it has an extremely high melting point (5,475 degrees Fahrenheit), making it extremely heat resistant, and an extremely low freezing point (crystallisation temperature of -395.4 degrees Fahrenheit), making its tensile strength extraordinarily high at low temperatures.
Dr. Bruce Banner discovered that during a previous Chitauri attack, the Hulk had been able to smash through the Vibranium plated Chitauri ships without any effort. Because of this, he discovered that Vibranium turns brittle when exposed to gamma radiation.
Although vibranium is susceptible to damage, it's depicted as the most durable material in the Marvel Cinematic Universe. The fact that Thanos possesses enough power to beak vibranium is a testament to the strength of the Mad Titan, but more importantly, the weapon itself.
Swords, knives, and more have been used against Hulk and almost none of them even leave a scratch or mark on him. However, with that said, there are two bladed weapons that can cut into Hulk's skin.
Much like vibranium, Nth metal is extremely strong, durable, and somewhat rare in its supply, but has also been known to hold abilities that far exceed anything vibranium is capable of.
What is the closest thing to Vibranium in real life?
James Kakalios, a physics, and astronomy professor at the University of Minnesota suggests a substance known as graphene would be the closest substance to vibranium known to man. Graphene is an ultra-thin form of carbon; only one atom thick.
Short answer: Not enough. Superman is ridiculously powerful, capable of bench pressing the Earth for days, without tiring. A full-power punch from someone that strong is going to overload the suit, and would likely kill Black Panther.
With his near-immeasurable strength, an ability to take even the most devastating blows, multiple attacks that aren't just punching, along with his flight and speed, the Hulk would struggle to keep up with Superman. Even in the few times he's faced Superman, the green monster has lost.
No. Thor's hammer is extremely durable. We've seen Superman hit with things before that didn't break. The only way I see a fight with Thor & Superman ending with Mjolnir broken is if Superman punched it as hard as he could while Thor was swinging it as hard as he could.
Fans love to debate who'd win a fair fight - Superman or the Incredible Hulk. In the past, the Man of Steel has won over the Green Goliath, however in a surprising moment, DC confirmed that Marvel's Green Goliath is absolutely capable of killing their flagship characters.
Thanos is crazy strong and using his Vibranium double-edged sword against Cap's Vibranium Shield, he is able to break the shield. In conclusion, Thanos' blade is not made of Uru instead its made of Vibranium.
Mined only in Wakanda, the metal is associated with Black Panther, who wears a suit of vibranium and Captain America, who bears a vibranium/steel alloy shield.
Well the hammer doesn't need to be of vibranium. Thor hammers is made out of uru metal which is one of the rarest metal in nine relm of marvel universe. Uru metal is as durable as pure adimantium (The thing out of which Wolverine skeleton is made ).
Deadpool is easily one of the most powerful characters Marvel has. The fast-talking gunman seems almost fearless on the battlefield, but in reality, there's a lot that scares the Merc with the Mouth. There are two things though, that scare him above all: cows and clowns are a Deadpool weakness.
Despite his immense power, the Hulk has been defeated by heroes like Wolverine, Iron Man, Puck, and the Punisher. Spider-Man, Fantastic Four, and the Thing have also managed to take down the Hulk using their intelligence, teamwork, and unique abilities.
The Hulk's skin is nearly impenetrable and his lung capacity allows for long periods of submersion in water, exposure to many forms of gases, and even to temporary survival in the airless vacuum of outer space.
Because without altering any continuities, if Fox's Wolverine and Marvel's Captain America were to come to blows, the claws would slice through the shield like a hot knife through butter. Vibranium can absorb kinetic energy, but it isn't indestructible (as evidenced by Thanos destroying the shield in Endgame).
Clearly, Thanos is aware he wouldn't be able to lift it. Although it's hard to pinpoint what exactly makes someone worthy of using Mjolnir, as it's ultimately determined by Odin, who placed the enchantment on the hammer, some believe one's worthiness is measured by traits like courage, honor, and selflessness.
Mjolnir doesn't damage Cap's shield at all, as shown below. I think it is fairly safe to assume that Stormbreaker (being a cutting weapon, rather than Mjolnir which is designed to smash or build) would inflict similar damage to the shield as Thanos sword does. Conclusion: Stormbreaker minces Cap's shield.
