Anodizing

MIL-A-8625 Type II class 1 (non dyed)
MIL-A-8625 Type II class 2 (dyed)
MIL-A-8625 Type IIB
ASTM B580 Type B thru F

Anodizing is performed to develop a layer of natural oxide on aluminum. This process provides your components with a non conductive coating that will enhance corrosion resistance and wear as well as provide color if desired. Choose from a wide range of standard colors with the availability of additional special order colors.

A note about color:
Although a wide variety of colors are available, exact matching to a pantone or federal standard is not generally possible. These standards are largely only applicable to inks or paints, however, they can be a useful tool to approximate dye for the closest match available. Due to multiple varying factors in anodizing, there will always be some variation in color from lot to lot.

Hardcoat Anodize

MIL-A-8625 Type III class 1 (non dyed)
MIL-A-8625 Type III class 2 (dyed)
MIL-A-63576 Type I

Hardcoat anodize provides a denser, thicker coating commonly used when increased wear and corrosion resistance is required. The coating can be dyed, with black being the most common color. Other colors are available however, they will be darker and less vibrant due to the darker color of the natural oxide. Typical thickness range is .0005 – .002 with .002 being the default. Sealing is standard on dyed coatings and available on non dyed coatings. We offer nickel acetate, sodium dichromate and boiling deionized water seal. PTFE Teflon application is also available.

Chromate conversion for aluminum commonly referred to as chem film, irridite or alodine provides a conductive finish to protect from corrosion as well as a base layer for a secondary coating. Its color can range from colorless to iridescent yellow or gold. The RoHs compliant version is available in colorless only.
