I think Gene is questioning the suppliers who list brass as "not heat treatable". He's right - annealing is a treatment that involves heat, so yes, brass can be heat-treated. But since 99% of people think of "heat treating" and "hardening" as the same thing, the vendors are covering themselves. You can't harden brass by heat treating. Why don't they say that? Who knows? Who cares....
