Prodn. of copper and chromium melts - by electro-melting in which component is added to electrode powder as hydride

摘要

Melts made of Cu, Cr and at least one component with a high oxygen affinity is produced by electro-melting an electrode made of a powder mixture of Cu,Cr and a hydride of the component. The component may be Zr, Ti, Hf, V, Nb and/or Ta. The hydride powder has a grain size of below 300 mm. USE/ADVANTAGE - Producing alloys which do not have a microscopic separation of Cu and Cr. In manufacturing switch components. The component having the high oxygen affinity can be directly introduced during melting without fear of producing pores and a high oxygen content. Also enable uniform distribution of the component.
