The invention provides Al2O3 particle-reinforced spheroidal graphite cast iron and further provides a preparation method of the Al2O3 particle-reinforced spheroidal graphite cast iron. A spheroidal graphite cast iron material is subjected to component reinforcement. The spheroidal graphite cast iron material is subjected to technological reinforcement. Powerful combination is achieved through combination of component reinforcement and technological reinforcement, thus according to the spheroidal graphite cast iron material, the tensile strength sigma b is larger than or equal to 620 MPa, the yield strength sigma 0.2 is larger than or equal to 530 MPa, the elongation percentage delta is larger than or equal to 12%, the hardness HB is larger than 260, the high strength and high ductility areachieved, and the wear resistance is high.
