Anodizing of Aluminum

Anodizing is an electro-chemical process that converts the aluminum surface into a durable, corrosion-resistant, anodic oxide finish. Anodizing is accomplished by a process of immersing the aluminum into an acid electrolyte bath and passing an electric current through a medium. Anodizing is widely known to be a very environmentally sustainable process, as it elongates the service life of the aluminum, all the while being a water-based process, generating no hazardous byproducts, and using no VOC's, halogenated hydrocarbonous substances, or other potential pollutants. For further information on the process, please make an inquiry. 

Types of Anodizing

  • Type II Sulfuric Acid [per MIL-A-8625F Class 1 (undyed) and Class 2 (dyed)] (variety of colours available)
  • Type III Hard Coating [per MIL-A-8625F Class 1 (undyed) and Class 2(black)]

Pickling & Passivation of Stainless Steel

 · Pickling is a process that removes stains (from welding), rust, or scale. This process is done through a nitric acid paste that is applied to the stainless steel surface.

· Passivation is a process that maximizes the natural corrosion resistance of stainless steel. It can remove surface contamination, such as particles of iron from reworking with cutting tools that can form rust.

Types of Passivation

  · QQ-P-35C Types II & VI

· ASTM A967

· AMS 2700

Chromate Conversion Coating

Chromate Conversion Coating is primarily used as a corrosion inhibitor, primer, or to retain electrical conductivity.

Types of Chromate Conversion Coating

· MIL-DTL-5541F Type I (yellow) Class IA & Class III

· MIL-DTL-5541F Type II (clear) Class IA & Class III (RoHS Compliant)
