Anodize Type II

Aluminum Anodize Type II is an electrolytic process that transforms the surface of aluminum into an aluminum oxide coating. The product becomes more durable, improving corrosion and abrasion resistance. Due to the porous nature of the oxide coating, the material now becomes a blank canvas where it is possible to dye it in a variety of different colors, or it may also be silkscreened and imprinted with graphics, as required.
