Connectors which are essentially, by weight, 85% to 93% copper, with silicon in the amount of 1.5% to 2.5% is disclosed. The balance of the material is zinc, desirably in the range of 5% to 12%. Trace elements of tin, lead and aluminum can be tolerated but should be minimized to less than 0.05%. Ideally the material is 81% to 91% copper, 1.75% to 2.4% silicon and the balance zinc of 6% to 10%. The traces may be 0.05% tin, 0.01% lead, and 0.005% aluminum.
