ABSTRACT:
A copper base alloy and process of treating same. The alloy consists essentially of: about 1.0 to 4.5% silicon; about 1.0 to 5.0% tin; about 0.01 to 0.45% chromium; and the balance essentially copper. Preferably, the chromium level is less than about 0.12% in order to provide good tool wear characteristics.
