A copper base alloy having a combination of strength and electrical conductivity which make it a suitable replacement for the C.D.A. 400 series tin brasses. The alloy contains from about 0.5 to about 2.8 percent iron and, preferably, from about 1.0 to about 2.0 percent iron; from about 0.2 to about 2.0 percent cobalt and, preferably, from about 0.3 to about 1.0% cobalt; from about 5 to about 15 percent zinc and, preferably, from about 7 to about 13 percent zinc; provided that the sum of the iron plus cobalt should be from about 0.8 to about 3.0 percent and, preferably, from about 1.5 to about 2.5 percent. |
