CHARGE FOR PRODUCTION OF MATERIAL FOR HIGH-CURRENT CONTACTS AND METHOD OF ITS PRODUCTION Russian patent published in 2014 - IPC C22C1/05 B22F3/14 H01H1/27 C22C9/00 

Abstract RU 2523156 C1

FIELD: metallurgy.

SUBSTANCE: proposed composition contains the following substances, in wt %: copper particles - 20-85, titanium hydride particles - 1-10, graphite particles making the rest. To make material billet, this charge is sintered by feeding electric current pulses there through, current density making 200-500 A/mm2, with simultaneous single-axis reduction.

EFFECT: high-density material, required resistivity, reliable wetability of graphite particles by copper.
