Abstract: Non-cosmetic quality aluminum substrates are given a cosmetic finish by applying a PVD coating to the substrate. An enclosure for an electronic device can include an aluminum substrate including a 6000 series aluminum or 7000 series aluminum, a PVD coating disposed on the substrate, and a protective underlayer disposed between the aluminum substrate and the PVD coating.
