Get a bit of MDF or ply and mill a pocket out same size as the sheet of alloy.
Then smear a bit of PVA in the bottom, then a sheet of cartridge paper, then more PVA and then the sheet, clamp down with a heavy weight until the glue dries.
The pocket and the PVA will prevent it moving. Hot water will release it.
One thing to note with thin alloy sheet. Most is just decorative and is 99% pure which means it sticks like shìt to a blanket or even the tools.
Try to obtain what is called half hard, or even hard alloy sheet, this machines a lot better.John S -
