This makes MICRALOX® an ideal application in marine environments. Obviously, there is a lot of exposure for saltwater spray on a boat. Given aluminum's weight to strength ratio, it is an ideal material for nautical hardware.

Sanford Process Corporation, a division of Katahdin Industries, announces the results of a rigorous saltwater test on its anodic coating product, MICRALOX®. After 15,000 hours of exposure to 4-6% salt spray per MIL-A-8625F, aluminum treated with MICRALOX® experienced no pitting. Normal anodizing is expected to withstand 336 hours of saltwater spray. MICRALOX® passed 15,000 hours, or a 44X increase. Given that this is an accelerated test, the lack of corrosion after such an extended period indicates a very high capability to perform in real life conditions.
Saltwater ion corrosion is a leading cause of corrosion for aluminum, as the sodium and chloride ions easily react with aluminum. Over time, corrosion leads to mechanical failure of the metal. Therefore, to increase corrosion resistance in this area is to lengthen the useful life of the parts, and broaden the applications where aluminum parts can be used. According to Jack Tetrault, President of Sanford Process Corporation, “This makes MICRALOX® an ideal application in marine environments. Obviously, there is a lot of exposure for saltwater spray on a boat. Given aluminum's weight to strength ratio, it is an ideal material for nautical hardware.” Marine equipment using chromate coatings, an alternative for corrosion resistance, contain heavy metals. Chrome 6 is increasingly regulated, and will eventually be eliminated, as it is a carcinogen and has high bio-toxicity.
About Sanford Process Corporation
Sanford Process Corporation (http://www.sanfordprocess.com) is a leading provider of hard coat anodizing solutions and intellectual property to a range of well-known OEMs and their prime subcontractors worldwide, with an increasing presence in Korea and China. Sanford Process is the developer of MICRALOX® aluminum oxide coating with a microcrystalline barrier that revolutionizes anodizing. MICRALOX® produces a long-lasting, virtually indestructible surface that delivers dramatically superior chemical corrosion resistance and eliminates color fading resulting from super-heated steam cleaning. MICRALOX® treated aluminum is an excellent alternative to stainless steel, plastic and other materials chosen for their chemical stability but which add weight, complexity and cost at a lower thermal conductivity. Further information about MICRALOX® can be found at http://www.micralox.com.
Sanford is also the developer of SANFORD PRINT®, a permanent marking achieved by embedding ink deep into an aluminum hard coat. Completed before the oxide is sealed, the resulting print is secured below the surface and is invulnerable to abrasion, chipping and delamination.
