FIELD: metallurgy.
SUBSTANCE: proposed method comprises making iron melt with aluminium content of 9.8-19.7%, pouring said melt in metal mould placed in salt melt at 950-1100°C, cooling said melt and isothermal curing of crystallised casting at 950-1100°C for 0.5-2 hours.
EFFECT: higher strength due to compact graphite inclusions.
