Abstract
A phosphor bronze alloy excellent in migration resistance, which containing from 3.0 to 9.0% by weight of Sn, from 0.03 to 0.35% by weight of P, from 1.0 to 5.0% by weight of Zn, and the substantial balance of Cu and impurities. The phosphor bronze alloy according to this invention is excellent in the migration resistance as comparable with that of brass without degrading the solderability or electrical conductivity.
