ABSTRACT:
A tin-rich lead-bronze based forged and rolled material consisting of 9-12% of Sn, 2-8% of Pb, 1-2% of Ni and 88-78% of Cu, Pb is allowed to exist in a finely dispersed condition at the grain boundaries in the .alpha.-phase of the Cu-Sn-Ni ternary equilibrium diagram. Such finely dispersed condition is stabilized by forging and rolling to provide a texture substantially free of segregation.
