PURPOSE:To obtain a casting alloy which has exellent toughness, heat resistance and corrosion resistance, etc., and can bsorb the oscillation from the outside by oscillation-absorbing materials consisting of heat-resistant fiber layers braided into a grating or network shape by incorporating one or plural layers of such oscillation-absorbing materials into the casting alloy. CONSTITUTION:The cast iron such as gray cast iron or spheroidal graphite cast iron having toughness is used for a main body 1 of the casting alloy in the casting alloy cast by a known full-mold method. Plural layers of the oscillation-absorbing material 2... embedded into the casting by the above- mentioned full-mold method are incorporated into the main body 1. The materials 2 are the highly heat resistant fibers such as, for example, carbon fibers and are cast into the body 1 in the longitudinal and transverse directions thereof. The above-mentioned casting alloy has therefore not only the heat resistance and toughness but also the effect of absorbing the oscillation to be exerted from the outside by the oscillation-absorbing materials 2... incorporated therein.
