[Marvel Comics/Movies/MCU] Is Adamantium actually indestructible, or could it be crushed by something as strong as a hydraulic press that can crush cars and tanks?

Asking because Magneto seemed to be able to bend Logan/Wolverine's claws, and Silver Samurai cut off Logan's Adamantium claws. I don't really know if being "indestructible" is actually consistent, or if it's just a general statement.

In the comics, adamantium is all but impervious to physical damage, but it *can* be deformed or even broken in a handful of ways. Magic and reality warping are the big ones, but since adamantium's strength comes from the unique structure of its molecular bonds, anything that can alter those bonds can also alter adamantium.

That's why magneto is able to reshape it; his power effects the magnetic links between atoms, allowing him to manipulate adamantium just like any other metal. The Molecule Man, the Beyonder, Franklin Richards, and others could (probably) pull off the same trick.

In the Fox universe, adamantium is much weaker. Super-heated adamantium is able to cut through it, as you saw with Silver Samurai and Logan. It's possible, however, that this Logan's skeleton was secondary adamantium, which is essentially a failed attempt to recreate true adamantium in the lab. Secondary adamantium would be vulnerable to true adamantium.

In the MCU proper, we just don't know, because it hasn't appeared on-screen yet.
