Chemical Processing

We offer a complete suite of Nadcap and AS9100 approved chemical processing services across the United States.

Valence technicians are experts in aerospace wet processes, ensuring a flawless finish on all your parts. We offer processing for various alloys including, aluminum, steel, titanium and nickel based alloys.

With state of the art processing lines, we have the most diverse set of anodize capabilities which include, tartaric-sulfuric anodize, boric-sulfuric anodize, chromic, and hard anodize. Valence also offers unique capabilities such as phosphoric-acid anodize, as well as phosphate fluoride sol-gel for titanium. We’re the leaders in chemical processing for Boeing and Lockheed, with unique processing approvals for other suppliers such as Airbus, Bombardier and Safran.

Chemical Processing Services

Type I Anodize
  • Boric Anodize – Boric-Sulfuric Acid Anodize (BSAA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a non-chromated, environmentally friendly solution.
  • Tartaric Anodize – Tartaric-Sulfuric Anodize (TSA) is an alternative to chromic acid anodize (CAA), that builds a thin-film anodic coating and provides corrosion protection and a mechanical bond. This is a non-chromated, environmentally friendly solution – typically specified in Airbus programs like the A350.
  • Chromic Anodize – Chromic Acid Anodize (CAA) creates the thinnest anodic coating, while providing the same corrosion resistance as other types of anodization, such as boric or sulfuric.
Type II Anodize
  • Sulfuric Anodize – Sulfuric Acid Anodize (SAA) is used when hardness and abrasion resistance is required on a part, and creates a surface that is harder than traditional chromic anodizing.
Type III Anodize
  • Hardcoat Anodize – Hardcoat anodize is created is a sulfuric acid bath, but results in a much thicker surface anode coating than traditional sulfuric acid anodizing.
Other
  • Phosphoric Anodize – Phosphoric Acid Anodize (PAA) is most commonly used in bonding applications, as it provides a superior porous surface for bonding to composites.
  • Chemical Film or Chem-Film – Chemical film or chem-film is also known as conversion coating.
  • Nital Etch – Nital etch is a solution of nitric acid and alcohol, used to etch metals.
  • Passivate – Passivation is the process of creating an outer shield material for a part that helps inhibit future corrosion.
  • Phosphate Fluoride – Phosphate fluoride coating is used to inhibit corrosion, improve paint adhesion and to reduce damage in metal to metal contact applications.
  • Aluminum Etch – Aluminum etch is a process by which a thin layer of the surface is removed, prior to penetrant inspection, typically in caustic or alkaline baths or solutions. This enhances the identification of surface defects, prior to further processing.
  • Titanium Etch – Titanium is often etched prior to penetrant inspection using a variety of different acids, commonly hydrofluoric and or nitric acid.
  • Zinc Phosphate – Zinc Phosphate is a conversion coating for steel and aluminum, comprised of phosphate salts and phosphoric acid.
Valence performs all of these services to the highest degree of care, with approvals for most prime and military specifications. View our specs here.
