FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy field and can be used in mechanical engineering and tractor construction for manufacturing of mouldings from gray cast iron with pearlite structure of metallic basis. Ligature contains, wt %: copper 45.0-55.0; tin 5.5-6.5; silicon 15.0-20.0; calcium 0.03-0.2; aluminium 0.1-1.0; iron - the rest, herewith it is used in crushed shape with grain size 3.2-16 mm.
EFFECT: ligature is uniform by chemical composition, provides reduction of expenditures for manufacturing of moldings made of pearlite cast iron and increasing of suitable fractional yield while grinding.
