It occurred to me after I posted that copper does work harden. It just
doesn't get as brittle, or harden as quickly as brass. Back in a
metalsmithing class, we had to anneal the dreaded compulsory copper bowl
periodically to keep it malleable, the better to form it onto the inevitable
lop-sided hemisphere. For what it's worth.
