Hard Coat Anodizing
Hard anodizing is a phrase used to describe an anodizing coating where the need for surface hardness and abrasion resistance is the main criteria. The build up for hard anodizing is much thicker than your standard anodizing. The typical build up of this coating is 0.001î and also 0.001î penetration into the material. The color of the aluminum oxide build up depends greatly on the alloy of the aluminum material. The color can range from a champagne/gold hue to a dark gray.
MIL-A-8625 Type III
- Class 1: Specifies that there will be no dye applied to the finished part.
- Class 2: Specifies that there will be a dye applied to the finished part.
Base Materials that Anodize Type III can be applied include 1100, 3000, 5000, 6000, and 7000 series aluminum alloys. Please note that we are unable to hard anodize 2000 series aluminum due to the high copper content.
If you are in need of a long part anodized we have some of the longest anodizing tanks in Houston!
- Is Hard Anodize the same thing as a Type II Sulfuric Anodize?
- The answer is no! Hard anodize is a much thicker and abrasion resistant coating.
- Can you strip old anodized coatings?
- The answer is yes; however, it must be noted that stripping the anodic coating will cause some loss in the base material.
- Can I anodize parts with brass or steel fittings?
- The answer is no, the part being anodized must only be aluminum. Anything else will be destroyed in the process.
