i didn't want to heat the metal to 500 degrees, so i bent it cold - this is a tank badge on a 76 cb750k - it did bend ok.
i found it took a good bit of force to start the metal moving. but i had to back off rapidly on the bending force once the metal started to give - it was a little surprising. not like bending iron. it would be easy to overdo it with this kind of metal, whatever it is, and bend too much.
