COMMERCIAL ANODIZE - TYPE 2
Commercial clear or color aluminum anodizing (also known as sulfuric acid anodizing) is an electrochemical process that produces a clear oxide layer, usually less than 0.0010″ thick, on the surface of the metal. This oxide layer is extremely porous and hard. When colored, dye or ink is deposited into the pore structure and sealed. Sealing improves corrosion protection, locks the color in and stabilizes the surface. Sulfuric acid anodizing provides comparable corrosion resistance and better wear characteristics than chromic (Type I) acid anodizing. Surtronics offers Bright Dip available on clear or color anodize.
We offer nickel acetate seal, dichromate seal, and hot water seal, as well as teflon on all Type II Anodize
- Surtronics offers black, red, blue, green, purple, and gold. Please call for accurate descriptions and color comparisons.
- 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.
- Maximum size capabilities for clear and black: 144" x 24" x 40"
- Maximum size capabilities red, blue, green, purple, and gold:24" x 24"
Aluminum parts which require installation of dissimilar materials (steel bushings, dowel pins, ect.) should not be installed prior to processing. However these materials can be masked using the best available techniques, but this type of processing can only be done at the customers risk.
