FIELD: non-ferrous metallurgy, in particular, manufacture of articles from industrial silumins.
SUBSTANCE: method involves providing hydrogen charging at temperature of 730-750 C during 0.5-1 hour; performing age treatment by heating to temperature of 200-300 C and holding within indicated temperature range; cooling in air. Method allows industrial silumins with reduced linear expansion coefficient to be produced within temperature range of from 200 C to 300 C.
EFFECT: increased efficiency in producing of silumins having low linear expansion coefficient.
