Heat treating means applying heat to whatever material on earth. Hardening is one aspect of it, annealing another, softening or making malleable yet another. It is not to be expected hat all materials behave the same. Everyone knows that brass and other copper alloys harden by mechanical stress and soften by heating. Just try to straighten a copper wire by bending. Ferrous metals act different because of their crystal structure, changing from martensic to austenic (that right in English?) and back, which copper alloys don't have.
