Hard Coat Anodized Articles

Functional solutions for hard coat anodizing and sulfuric acid anodizing provide validated and non-exclusive processes that can be quickly implemented across a range of application needs, enhancing the functionality of your products. Typically these solutions will also meet common standards across a number of industries, including the Military’s Mil-A-8625. This is an existing tool kit that does not require process development allowing us to move quickly to address your specific finishing needs.

Solution: Revolutionary Chemical & Corrosion Resistance

The only anodic coating capable of withstanding a pH <2 & >13: Anodic coatings are readily stripped using strong chemistries, causing the coating to dissolve because of chemical affinity. How to address the need for chemically resistant anodic coatings that are RoHS compliant without losing the other values of the anodic coating? Through a patented process that phase-changes the amorphous oxide into partially micro-crystalline structures. This unique anodic process, branded MICRALOX®, reduces the rate of dissolution by a factor of 10 X while providing the other benefits of a QUANTUM® Hard Coat, and other conventional hard coat anodizing. This coating exceeds the requirements of Mil-A-8625.

Solution: Exceptional Dielectric

The only anodic coating with a dielectric >1500 ohms: With attainable coating thicknesses of over 60 microns, coupled with the dielectric properties of micro-crystalline anodizing, exceptional dielectrics can be achieved up to 2,500 ohms.

Solution: Unbeatable Salt Water Spray Resistance

The only anodic coating that can withstand >15,000 hours of salt-water spray testing without failure: MICRALOX® provides exceptional salt water spray resistance without the need for chromium or other heavy metal compounds. RoHS compliant, micro-crystalline anodizing provides a proven solution for many marine coating applications and other corrosive environments where conventional anodizing and hard coat do not perform. Exceeds the requirements of Mil-A-8625.


Solution: Flexible Substrates

The only anodic hard that does not craze or crack on thin substrates: How to produce a hard coat on a flexible substrate that does not crack and craze but does give very high abrasion resistance? Sanford Process’s Low Voltage hard coat rectification allows flexible coatings that can be designed to meet your specific application needs. Meets the requirements of Mil-A-8625.

Solution: Reclaim Lost Dimension

The only anodic hard coat with a hard coating >60 microns: Why stop building hard coat thickness at 60 microns? Because that is the capability of conventional hard coat anodizing at which point the resistance of the coating disallows further coating formation. However, with Sanford Process Salvage™ Process coatings can continue to be built up to 150 microns, allowing parts to be brought back into tolerance or rebuilt from usage. This can save considerable expense where re-milling new parts is the alternative. Meets the requirements of Mil-A-8625.

Solution: No Burn 2000 Series Aluminum

The only successful hard coat process for 2000 Series Alloys: The Sanford PLUS® Process is specifically designed for 2000 series alloys that prevents burning and gives exceptional hard coat properties. Whether you work with 2011, 2024, or other high-copper aluminum alloys, Sanford PLUS® can be provide a very hard, functional coating at 2 mils or greater. Meets the requirements of Mil-A-8625.
