The invention discloses a universal aluminium alloy air-conditioner foil and a manufacturing method thereof. The universal type means to the punching processing technology suitable for various punches. The universal aluminium alloy air-conditioner foil is characterized in that as for the alloying elements distributed in Al base, the weight ratio of Fe to Si is controlled to be 4-6:1, so that the aluminium alloy air-conditioner foil tends to Fe causing 45-degree earing and tends to Si causing 0 or 90-degree earing combined action in the punching process so as to improve the evenness of earing direction.
