Abstract:
A highly stiff and highly damping cast iron containing C and Si in an amount of 3.30 to 3.95% in terms of carbon equivalent shown in the following equation (1), Mn: 0.25 to 1.0%, P: 0.04% or less, S: 0.03% or less, Al: 3 to 7%, and Sn: 0.03 to 0.20%, balance being Fe and unavoidable impurities: Carbon equivalent (%)=C(%)+(1/3)×Si(%) (1).
