ABSTRACT:
Lead-free metallurgy powder for use in manufacturing a shaped bronze part by powder metallurgy techniques which consists essentially of a substantially homogeneous blend of about 90 parts copper, about 10 parts tin and an amount of bismuth in the range from an amount effective to improve the machinability of the shaped bronze part up to about 5% weight are disclosed. Lead-free metallurgy powder for use in manufacturing a shaped bronze part by powder metallurgy techniques which consists essentially of a substantially homogeneous blend of about 70-90 parts copper, about 10-30 parts zinc and an amount of bismuth in the range from an amount effective to improve the machinability of the shaped bronze part up to about 5% weight are also disclosed.
