The melting technology of receiving, structure and some properties of Cu—30% (mass.) Cr for arc broken electrical contacts in vacuum switch camera

Abstract

The ingots of Cu-30Cr alloy by mass 2,6-8,7 kg by arc smelting with expendable electrodes were smelted. Electrodes were assembled from sintering bar containing 70% Cu-30% Cr and from ingots of alloy Cu-30% Cr of inductional melt. The dates about structure, density, mechanical and electrical properties of alloy a so the height of ingots and concentration of gas and other impurities were presented. Full text download
