I'm trying to shape it to make a part.
A crane may be your solution! Some cranes can hold more than 15metric tons of loadSo you may need to get a few of these to suppor your 50 ton hovering townThe tricky part would be identifying the critical load points to equally distribute this loadAnd of course an even plane, maybe fiber glass or a light rigid material, kevlar? where the hovering town could 'sit'You can call that your foundation.
There are different alloysSome if you try to bend-it it will crack and breakSome are easy to machine, some just sticks to the tool, and is hell on earth! 3/8 are plates1/8 are sheetsNot the same price per pound… You need to get samples to try out Hope this properly answers your question
