Anodized Aluminum

Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish.  This process allows the anodized aluminum to be dyed a variety of colors before sealing.  Stylmark offers over 1,000 anodized aluminum color and finish combinations.  Stylmark also has the ability to match a specific color to meet your brand needs. 

Stylmark is a Type II anodizing facility located in Minneapolis, Minnesota. Type II anodizing is defined as conventional coatings produced from sulfuric acid baths.

Benefits of Type II Anodizing include:

  • Increased corrosion resistance
  • Increased surface hardness
  • Improved lubricity
  • Improved adhesion
  • Allows dyeing (anodized coloring)
  • Lower thermal conductivity
  • Lower coefficient of linear expansion

Anodized finishes have made aluminum one of the most respected and widely used materials today in retail and commercial environments.  Anodized aluminum was used in one of the world's tallest buildings --- the Sears Tower in Chicago, IL.  Anodized aluminum is a perfect choice for high-traffic areas as it has the hardness surface that can be compared to a diamond.

Stylmark only uses aluminum alloy 6463 because it is ideal for achieving a bright finish on aluminum.   Stylmark can anodize customer-supplied material in aluminum alloy 6463 for large-volume projects.  Stylmark’s anodizing tanks can accommodate material up to 146” x 38” x 18”.  Please contact Stylmark’s estimating department at to see if we can assist in your anodizing needs.
