An aluminum article includes a substrate made of aluminum or aluminum alloy, a porous aluminum oxide layer formed on the substrate, and a transparent vacuum coated layer formed on the aluminum oxide layer. The aluminum oxide layer has a top surface and a plurality of pores defined therein. The pores run through the top surface and each pore is formed by peripheral wall and bottom wall. The vacuum coated layer covers the top surface as well as the peripheral walls and bottom walls of the pores, thereby forming a profile corresponding to the aluminum oxide layer.
