Comment on How can an airplane hit -47°c (-52°f) temperatures while flying over Southern Florida?
Skullgrid@lemmy.world 17 hours agothanks for the explanation. So because of the single crystal(??) they don’t melt since it changes the melting point?

The crystallization is mainly about strength so they don’t snap or deform at a billion rpm, because typical aluminum would shatter under the load. They don’t melt because of magic. www.youtube.com/watch?v=QtxVdC7pBQM
