THESE ALLOYS ARE DEPOSITED ON A METAL SUBSTRATE IN THE FORM OF WIRE OR THE LIKE, PREFERABLY A COPPER OR COPPER ALLOY SUBSTRATE BY ELECTRODEPOSITION USING A FLUOROBORATE BATH AND CAREFULLY REGULATED PH, CURRENT DENSITY AND TEMPERATURE CONDITIONS. THE RESULTING ALLOY COATED COMPOSITE PRODUCT PROVIDES AN ELECTRICAL CONDUCTOR HAVING GOOD SOLDERABILITY, FREEDOM FROM GALVANIC CORROSION AND TEMPERATURE CAPABILITIES WHICH FAR EXCEED TIN OR TIN-LEAD COATINGS ON COPPER CONDUCTORS.
