Possibility of electrodeposition of Ni–W alloy with the content of tungsten to 9.3 аt. % from the electrolyte containing malic acid as a ligand is shown. It is established that the deposit of an Ni–W alloy consists mainly of connection of Ni17W3. Microhardness of rainfalls of an alloy of nickel with tungsten reaches 5,7 GPa.
