Give up 30X steel: Cybertruck will use a custom alloy created by Tesla and SpaceX.

When Elon Musk announced his bullet-proof pickup, he promised that Cybertruck would be “almost impenetrable . . . Ultra-hard 30X cold-rolled stainless steel” made. But time is moving forward and Cybertruck is changing, and today (July 21 local time), Musk confirmed on Twitter that they have decided not to use 30X steel to make the outer skeleton of the electric pickup.

But fans shouldn’t be alarmed by the news, as Musk has found a better alternative. The company is understood to be working with SpaceX, another of Musk’s companies, to create a custom alloy for Starship and Cybertruck.

Musk is known for its vertical integration, while Tesla has its own in-house materials engineers to make new alloys.

Whatever material Musk uses, it’s safe to say that the final version of the pickup will deliver on his promise to be the ultimate vehicle for the post-apocalyptic world.
