The invention provides a yellow aluminum alloy. The production process includes the steps that (1) the aluminum alloy is made into fine powder with the fineness ranging from 150 meshes to 180 meshes; (2) a forming agent is added into the aluminum alloy fine powder obtained in the first step, and the mixture is stirred and mixed at a high speed for 20 minutes; (3) yellow pigments are added into the mixture obtained in the second step, and the mixture is stirred and mixed at a high speed for 40 minutes; (4) the mixture obtained in the third step is heated to 680 DEG C to 700 DEG C, the molten mixture is stirred at a high speed till bubbles are generated in the mixture, and stirring is conducted continuously; (5) the mixture is continuously stirred for 30 minutes, the temperature in the fourth step is kept till no bubbles is generated in the mixture, heating is stopped, cooling is conducted, and the yellow aluminum alloy is obtained. The yellow pigments are chrome antimony titanium buff rutile, and the yellow pigments consumption occupies 5% to 7% of weight of the aluminum alloy. The yellow aluminum alloy has the advantages that the inner color of the metal confirms to the outer color of the metal, the produced products will never fade, oil paint is not needed, the production cost is less, the production process is free of pollution, and thus the yellow aluminum alloy is a good environmentally friendly product.
