CuCr25W1Co1 electrical contact alloys were prepared by a vacuum smelting method and their properties were measured. The results show that selective strengthening by W and Co improves the breakdown fields of CuCr alloys, and that vacuum smelting is an effective method to produce CuCr contact material, it saves Cu and Cr, improves properties, and is suitable for large scale production.
