Abstract
PURPOSE:To obtain the titled cast iron having extremely high coefficient of thermal expansion, by controlling respective compositional limit values of C, Si, Mn, Ni, Mg and/or rare earth elements (RE), etc. CONSTITUTION:A cast iron having a composition consisting of, by weight, 1.5-3.5% C, 1.5-4.0% Si, 2.5-10.0% Mn, 5.0-20.0% Ni, <=0.20%, in total, of Mg and/or RE, <=3.0% Al, further <=0.2%, in total, of Bi and/or Sb, and the balance iron with inevitable elements is prepared. Moreover, it is desirable that the spheroidizing rate of graphite structure is regulated to about 30-<70%, or it is preferable that the spheroidizing rate of graphite structure is regulated to >=about 70%. Owing to the constitution as mentioned above, the cast iron having extremely high coefficient of thermal expansion and causing no disadvantages, such as deformation due to differential thermal expansion, when combined with the parts made of Al alloy can be obtained.
