X-Ray Spectrometric Analysis of Alloyed Copper

  • T. J. Cullen
Part of the Developments in Applied Spectroscopy book series (DAIS, volume 3)


Pure copper has properties which are desirable in only a few applications. Over the years, a series of alloyed coppers has been developed which changes only certain physical characteristics while maintaining the electrical and heat conductivities. These alloys contain only 0.01 to 3.0% of the alloying element(s). Production quality control of these alloyed coppers presents the problems of rapid and accurate analysis. At U.S. Metals Refining Company, these alloys are produced in a continuous casting operation. Master alloys are added, at a predetermined rate, in a hopper between an oxygen-free furnace and a continuous casting apparatus. This situation leads to sampling problems which are circumvented by taking drilled samples. The drillings are briquetted and placed in a rotating sample holder. Surface irregularities are compensated by the use of scattered radiation intensity ratio techniques. Interelement effects of ternary and quaternary alloys are discussed, and sensitivities of various elements in copper are given.
