Brass can be bent, but it is subject to work-hardening, like copper. It should be annealed by heating it up to a faint red glow. Then it can be air cooled or quenched in water. It won't harden with quenching. Depending on how much work you are doing on the work piece, you may have to anneal it more than once.
