Anodize Overview

Sulfuric Anodizing is a process that provides a conversion on aluminum which changes the surface of the material to a naturally occurring aluminum oxide. The oxides build up changes the surface of the aluminum which then provides greater abrasion resistance as well as increased corrosion protection. Anodize ensures a part can resist corrosion and wear and tear from prolonged use, and that it retains its cosmetic appearance under any conditions.

Anodizing aluminum is an extremely durable post-processing method. Not only does it enhance the properties and appearance of a part, it enables better adhesion for paint primers and glues. This technique utilizes anodic films that provide unique aesthetic effects, such as transparent coatings that reflect light or thick coatings that can absorb dies.

Types Of Anodizing We Provide

Metal Chem Inc. has developed an approved immersion process in full compliance with NADCAP specifications – and provides two types and two classes of electrolytically formed anodic coatings on aluminum and aluminum alloys for non-architectural applications.

Type II & IIB

Sulfuric Acid Anodizing

Sulfuric acid anodizing, conventional coatings produced from sulfuric acid bath. Type II coatings are the result of treating aluminum and aluminum alloys electrolytically in a bath containing sulfuric acid to produce a uniform anodic coating on the metal surface. Anodizing metal removes the conductivity from the part which is required in certain industries like aerospace and military & defense.

Corrosion resistant, available in several color options, and extremely cost effective. Sulfuric anodize coating is a popular service for many of our customers. Sulfuric anodizing yields a coating slightly thinner and less abrasion-resistant surface than hardcoat anodizing.

Type III

Hardcoat Anodizing

Hard anodic coatings are the result of treating aluminum and aluminum alloys electrolytically to produce a uniform anodic coating on the metal surface, this process operation produces a heavy dense coating of specified thickness on aluminum alloys. Type III coatings shall not be applied to aluminum alloys with a nominal copper content in excess of 5.0 percent or nominal silicon content in excess of 8.0 percent. Anodizing metal removes the conductivity from the part which is required in certain industries like aerospace and military & defense.

AC7108/8 – NADCAP Audit Criteria for Anodizing

Type III (hardcoat) anodizing is thicker and denser than Type II (sulfuric acid), so it isn’t usually dyed. Where Type III anodize is utilized most is for wear-resistance purposes.

Anodizing is a valuable metal application across a variety of industries including:

  • Automotive
  • Aerospace and defense
  • Industrial & Commercial
  • Medical
  • Robotics
  • Energy
