Hard Anodize:
MIL-A-8625 Type 3,
AMS 2468, 2469, ASTM-B-580 Type A.
Features:
- Provides extreme abrasion resistance in coatings having .0005" to .004" thicknesses.

Anodize Color:
Features:
- Coloring of an anodized surface may be achieved by absorbing dyes of any color into the open pores of the anodized coating before they are closed by sealing which is part of the normal anodize process.
- Some dyes provide a permanent fade resistant color for long lasting outdoor exposure in architectural applications.
- Others provide an attractive sales enhancing decoration for consumer products for indoor use.

Etch:
Features:
- Controlled chemical modification of the smooth reflective aluminum surface inherent on extruded shapes or sheet products can enhance the eye appeal of aluminum products by etching in an acid or caustic chemical bath.
- Masking can be used to provide protection for the reflective surfaces that are desired to remain bright while adjacent surfaces are given a contrasting satin appearance.

Pickle:
Features:
- Pickling of metal is a process which softens and/or completely removes contaminating surface oxides or other inorganic materials in order to expose a basis material surface for use "as is" or ready for further surface finishing.
- It must be done with care to prevent attack of the product surfaces.
