and who's stronger materials here?

Where in the MCU is there ever a mention of "Uru"?

Mjolnir was "forged in the heart of a dying star." Nivedellir is that place, we see it in IW, and we see Stormbreaker forged. We know that the glove was forged there as well. But there is never any mention of Uru that I recall.

If you mean "what Mjolnir is forged from" - we see it smack Vibranium without destroying it utterly a couple of times.

Now, if we assume, as some have, that Thanos' sword is "Uru", well, it cuts Vibranium pretty casually. Buuuut - something equal in hardness will do that pretty easily if it has a fine edge and is swung into the other material.

So... equal-ish?
