FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and concerns cast iron compositions that can be used in mechanical engineering. Cast iron contains, wt%: carbon 3.0–3.5; silicon 1.5–2.0; manganese 0.6–0.8; aluminium 0.15–0.25; cobalt 0.12–0.16; copper 1.5–2.0; vanadium 2.5–4.5; boron 0.05–0.1; iron – the balance.
EFFECT: higher strength of cast iron.
