Abstract


Technology for making electrical aluminum alloys with different contents of rare-earth metals and nickel was developed. Cast and deformed semi-finished products made of new alloys were obtained as a result of experimental studies. The structure and mechanical properties of metal were studied as well as electrical resistivity measurements of rods and wires were carried out. The effect of nickel and rare-earth metals on these characteristics was found out and alloy compositions with the most favorable combination of strength and electrical properties were determined.
