Elon Musk is building Spaceship out of Stainless Steel.

Musk tweeted in January that the rocket formerly known as BFR would be
built of stainless rather than carbon fiber.

So SpaceX is making a huge rocket out of stainless steel. This marks the first
time the material has been used in spacecraft construction since some
early, ill-fated attempts during the Atlas program in the late 1950s.
The state-of-the-art carbon fiber forming the body of the Starship rocket
(formerly known as the BFR, or Big Falcon Rocket, or Big F-other-word
Rocket) and its Super Heavy booster would be replaced by 300-series
stainless.

Elon Musk Quotes “We do have a great materials group, but initially we will
simply use high-quality 301 stainless. There’s an important other thing that
makes a big difference. For ascent you want something that’s strong at
cryogenic temperatures.”
