Abstract
Replacement of copper during production of current-conducting busbars by aluminium clad with a thin layer of copper allows reducing metal intensity of products preserving the high electric conductivity. The technology of manufacture of coaxial copper-aluminium current-conducting rods using explosion welding and drawing was offered. The modes of heat treatment of rods after drawing were experimentally selected providing the required mechanical properties at a minimum number of forming intermetallics. The methods of calculation of sizes of initial billets providing obtaining the required geometric parameters of a product were described. The possibility of application of explosion reduction of billets instead of explosion welding is shown. 5 Ref., 2 Tables, 7 Figures.
