Copper will work harden when being bent or hammered on. To soften it again heat it up kinda red and quench in water just the opposite of steel. I had to do some tricky bending on copper water pipe ( packed with sand ) where I had to soften it several times. When I was done forming, the pipe was dead soft from heating and quenching to harden it back I just wiggled it back and forth and you could feel it harden back up. Bill,
