The invention relates to metallurgy, particularly to production of alloys, the composition of which provides hydrogen absorption and extraction. The process includes not less than four remeltings having the following ingot solidification rate less than 0,6 mm/s, and the following ingot solidification rate more than 0,6 mm/s in the last remelting. The invention allows to increase efficiency of REM alloy production process by 2,5 times at standard equipment and provides production of alloys having high technical features and stable properties for using as components of thermal pumps and hydrogen accumulators.
