Abstract The present invention relates to metal material. Al-Sr intermediate alloy is manufactured through the steps of: mixing industrial pure strontium carbonate, aluminium oxide, potassium borofluoride and potassium chloride in a certain proportion, putting the material on the surface of molten aluminium, powering the molten aluminium with DC current for 20-60 min and final casting molten aluminium in metal mold or casting and rolling into string. The intermediate alloy has excellent Al-Si alloy modifying effect.
