FIELD: metallurgy.
SUBSTANCE: invention relates to non-ferrous metallurgy and can be used for preparing composite materials based on aluminium or aluminium alloy using foundry technologies. Ligature comprises aluminum and carbon nanotubes (CNT), surface of which contains adsorbed gases at weight ratio of CNTs and adsorbed gases of not less than 100, wherein at least part of CNT is located in volume of aluminium or its alloy without contact with environment.
EFFECT: invention enables to obtain ligatures for aluminium and aluminium alloys to obtain composite materials based on aluminium or aluminium alloys with uniform distribution of CNTs therein.
