Clear in appearance, a sulfuric acid anodized coating is a very popular coating for decorative use with good corrosion resistance. This is a porous coating which is ideal for applying dyes.


Boric Sulfuric Acid Anodize has superior corrosion resistance and excellent base for paint. This coating is a substitute for chromic acid anodize.


This traditional anodize coating process system is corrosion resistant and a very good base for paint.


Hardcoat produces a heavy dense coating that provides greater wear resistance and corrosion protection. This coating can also be dyed a variety of colors.

Chem Treat

Chemical Treatment #7 (Dow 7): The dichromate coating is light to dark brown in appearance. It provides a good paint base and fair corrosion resistance. This treatment causes no appreciable dimensional changes to the parts.

Chemical Treatment #17 (Dow 17): Appearance ranges with thickness from light green to dark green. The coating thickness is an average of 1.5 mil. Dow #17 provides an excellent paint base and reasonable corrosion resistance on all forms and alloys of magnesium. It also provides hardness and abrasion resistance similar to anodized finishes.

Chemical Treatment #19 (Dow 19): Dilute chromic acid gives this coating a brassy appearance. Dow #19 is an excellent touch up for either Dow #7 or Dow #17 process. It also provides a good base for pigmented lacquers and enamels.
