The invention relates to metallurgy, particularly to production of alloys, composition of which makes hydrogen absorption and extraction possible. The process consists of no less than four remeltings with the following ingot solidification rate of no 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 about 2,5 times at standard equipment, and provides production of alloys with high technical features and stable properties for using them as components of thermal pumps and hydrogen accumulators.
