FIELD: metallurgy.
SUBSTANCE: invention relates to the field of ferrous metallurgy, particularly to cast iron compositions, which can be used in machine building. Cast iron contains, mass %: carbon 2.2–2.7; silicon 0.9–1.7; manganese 0.7–0.9; copper 0.25–0.35; yttrium 0.03–0.04; praseodymium 0.09–0.13; nickel 1.3–1.7; tungsten 0.15–0.2; tellurium 0.0008–0.0012; iron – the rest.
EFFECT: technical result is increasing of cast iron durability.
