Show In Speeding Communications . .. NOTHIMG SERVES LIKE COPPER THE USE of electricity as a means of communication started with telegraphy. Then came the telephone, radio and television. Many of today's war pictures are radio-transmitted from distant battle fronts. From days to seconds has been the progress of communications since 1844. Copper and its alloys have made important contributions to this dramatic chain of developments. From the beginning, advantage has been taken of the superior electrical conductivity of copper and the ready workability of brass for intricate and accurately machined parts. Phosphor bronze, another copper-base SELENIUM COPPER, a new alloy developed by The American Brass Company, combines high electrical conductivity, free machining and hot -working properties, and is much in demand for glass-to- copper seals in vacuum-tight electronic tubes. AN alloy which combines excellent spring qualities with current-carrying capacity, also renders dependable service in equipment of all descriptions. To realize the importance of copper, consider that every one of America's 26,000,000 telephones represents 80 pounds of the red metal at work in plants, equipment and transmission lines. For more than a century, The American Brass Company has played a leading role in making these useful metals available. Research continues, and new and improved copper-base alloys will be ready to serve the expanding needs of American Industry.
