What material was Thanos’s sword and armour made of? And who made them?

It is made out of uru metal Made by eitri.

It could have been Vibranium.. What do you think?

Don’t think so. Black panthers suit too is made of vibranium, and all it could do was scratch the paint off the shield……

It was actually made of uru… And made by eitri… In the comic Thanos: Titans consumed, Thanos describes as almost being killed by an asguardian sword which he removed from his chest and kept it for himself… This might actually be the sword which we see in endgame

I think it was made of uru metal by the asgaurian eitiri
