Decorative and corrosion-resistant electrochemical finishing for aluminum sheet metal — clear, black, and full-color dye options that bond into the metal itself, not on top of it.
Type II anodizing is an electrochemical process — not a paint or coating. Aluminum parts are submerged in a sulfuric acid bath and charged as the anode. Oxygen liberated at the surface reacts with aluminum to grow a hard, porous oxide layer that is part of the metal itself. Once dyed and sealed, the finish cannot peel, chip, or flake.
Pick a swatch to load that anodized color into the right side of the slider. Drag left or right to compare it against a clear (untinted) anodize on the same alloy — the dye-infused finish on the right is the only difference.

Untinted Type II finish. Preserves the silver tone of the underlying aluminum — ideal when you want the corrosion and hardness benefits of anodize without changing the part's color.
Deep matte black — standard for AV racks, broadcast panels, and any product where reflected light is unwanted.
Type II anodizing is an aluminum-only process. Different alloys take dye differently — the silicon, copper, and magnesium content all affect final color depth, evenness, and appearance.
A few callouts on your drawing prevent the most common anodizing problems — and protect critical features from being affected by the bath.
Every aluminum alloy, finish, and gauge we anodize, with how each one takes dye. Each thickness shows the finished dimension after a standard 0.0007″ coating — anodize grows the part, it does not sit on top of it.
Upload your DXF or STEP file and select Type II anodize during quoting. Choose your color, callout class, and we handle every step in-house before shipping.
