Abstract

A thixocast casting material is formed of an Fe&mdash;C&mdash;Si based alloy in which an angle endothermic section due to the melting of a eutectic crystal exists in a latent heat distribution curve and has a eutectic crystal amount Ec in a range of 10% by weight<Ec<50% by weight. This composition comprises 1.8% by weight&lE;C&lE;2.5% by weight of carbon, 1.4% by weight&lE;Si&lE;3% by weight if silicon and a balance of Fe including inevitable impurities.
