In the ending scene of Avengers: Endgame movie, Iron Man created his own
Infinity Gauntlet. First Hulk snapped it to undo the decimation by Thanos in Avengers: Infinity War, after that Iron Man used it to kill all the enemies.
How come the material used in Iron Man's
Infinity Gauntlet could survive two snaps and the massive power of all six Infinity Stones? We do know that Thanos' gauntlet was made of material similar to Mjölnir and Stormbreaker.
How could Stark's item be used more times than the previous version?
