The Naval Undersea Warfare Center Division Newport has developed, tested, and patented Altite, a suite of technologies that use titanates in a drop-in process to replace hexavalent chromium commonly used to prevent corrosion on metals. The process also eliminates the need for ferro-cyanide in the bath, further reducing toxic elements and waste streams. Altite offers superior bonding performance compared to chromated products, especially in bonding titanium to carbon fiber composites.
Altite meets a variety of MIL-SPECS, including MIL-A-8625F for aluminum and aluminum alloys, and MIL-C-5541E for conversion coatings on aluminum. Product and application costs are competitive with existing processes. Personnel exposure concerns are vastly reduced compared to chromated products.
- No Chrome: Completely chrome-free technology utilizing titanate chemistries to impart corrosion resistance and establish superior bond strength
- No Cyanates: Altite does not not require the use of cyanates in the bath, further reducing costs, eliminating toxic materials, and lowering personnel exposure risks
- Broad Applications: NUWC has developed titanate-based no-chrome formulations for primers, etches, and conversion coatings for use on a variety of metal surface
- US Patents: 7,101,808; 7,022,254; 6,706,207; 7,572,324
- Potential for collaboration with Naval Undersea Warfare Center Division Newport researchers
