You make a valid point, but you neglect to mention that the same temperature/pressure regimes that generate ice crystals also make metals (especially scrap metal alloys) very brittle and prone to cracking, not to mention long-term effects on malleability.
You have a point there. If you want to build something out of metal and not have it break—and there are lots of important things that can be made out of metal—a cold environment makes it harder.

Kind of a big thing to leave off!
