After machining, brass parts are often annealed (softened) for subsequent bending, swaging or crimping. A partial anneal
down to 6010 RB is recommended for 90 bends, a full anneal down to 3515 RB is recommended for pins or terminals
that are swaged (riveted) to a circuit board or crimped to a wire.
RoHS-2 directive 2011/65/EU, exemption 6c allows up to 4% lead as an alloy agent in copper.
