This paper studied iron-ductile metals with incubation/spheroidization treatment and adjustable graphite ball density. Using analytical methods like Scanning Electron Microscopy (SEM), ultrasonic thermal melt loss weight, the paper systematically studied the effects of different nodular graphite densities on the hot melt loss properties of iron-ductile metals. The results show that with the increase of ductile density, the weight of hot melt loss of iron-ductile metal gradually decreases, the molten aluminum corrosion resistance of iron-ductile metal is significantly improved compared with that of H13 steel. After the iron-ductile metal immersion thermal melting experiment, the thickness of the Fe-Al reaction product layer is inversely proportional to the ductile density, the graphite spheres with small spacing and large specific surface area hinder the contact between the molten aluminum and the matrix, diffusion of molten aluminum, thereby inhibiting the corrosion of the matrix by molten aluminum. Iron-ductile metals exhibit better resistance to aluminum melt corrosion.
