The present invention discloses a method for producing an aluminum-zirconium-titanium-carbon (Al—Zr—Ti—C) intermediate alloy; the Al—Zr—Ti—C intermediate alloy comprises 0.01% to 10% Zr, 0.01% to 10% Ti, 0.01% to 0.3% C, and Al in balance; the producing method comprising the steps of: preparing commercially pure aluminum, zirconium, titanium, and graphite material according to the weight percentages of the aluminum-zirconium-titanium-carbon intermediate alloy; the graphite powder is subjected to the following treatments: being added to the aqueous solution of KF, NaF, K2ZrF6, K2TiF6 or the combination thereof, soaked for 12 to 72 hours, filtrated or centrifuged, and dried at 80° C. to 200° C. for 12 to 24 hours; melting the commercially pure aluminum and keeping it at 700° C. to 900° C. to provide aluminum liquid, in which the prepared zirconium, the titanium and the treated graphite powder are added and melted to provide an alloy solution; and keeping the alloys solution at 700° C. to 900° C. under agitation and performing casting molding. The present method produces a high-quality Al—Zr—Ti—C intermediate alloy in low cost.
