  • Metallurgy question: I want to chop up a drinks can to make a cookie cutter, but the metal is really springy and difficult to shape.

    Is there some kind of heat treatment I can do to make it more pliable? I have a gas hob at my disposal

  • Annealing (heating) will help soften hardened alu, how easy this will be on a drinks can, I can't really say!

  • Sounds like steel cans are the better way to go, but I'm still interested to try annealing the alu cans to see what happens.
