Examples of an anti-fingerprint enclosure for an electronic device have been described. In an example, the enclosure comprises an aluminum alloy substrate; a sealing layer deposited on a surface of the aluminum alloy substrate; and a magnesium fluoride sol-gel derived film deposited on the sealing layer, wherein the magnesium fluoride sol-gel derived film exhibits a refractive index of from about 1.36 to about 1.44.
