Abstract (en)

[origin: EP0586197A2] Two-phase, alpha + beta , brasses are rendered lead-free while retaining properties - notably, hot working properties. Supplementing bismuth, as substituted for lead with either of the elements phosphorus or indium, assures retention of the hot working properties associated with the conventional, lead-containing "forging" and "architectural" brasses.
