Abstract

PURPOSE:To produce a casting of a cast iron having excellent machinability by preparing the casting of the spheroidal graphite cast iron which contains specific ratios of C, Si, Mn, Mg, Sn, and Cu; is specified in the number of graphite grains; and has the base of pearlite structure. CONSTITUTION:The casting of the spheroidal graphite cast iron which contains, by wt.%, 3-4% C, 1.5-2.5% Si, 0.5-1.0% Mn, 0.005-0.08% Mg, and 0.01-0.1% Sn and/or 0.01-1.0% Cu, has >=250 pieces/mm<2> graphite particles and has the base of substantially the pearlite structure is prepd. The casting of the spheroidal graphite cast iron which has the excellent machinability and is improved in wear resistance and resistance to fatigue is thereby obtd. This casting is useful for crank shafts of automobile engines, etc.
