Anodizing aluminum

The environmental advantages of aluminum are widely acknowledged. Aluminum is one of the most durable and versatile of metals, offering improved mileage in automobiles by virtue of its lightweight and tremendous recyclability. According to the Aluminum Association, about one-third of all aluminum produced in the U.S. today is from recycled sources, saving some 95 percent of the energy required to produce aluminum from raw materials.

Anodizing is an electrolytic process used to place a protective oxide coating on aluminum. This coating can be dyed a variety of colors before sealing, and after sealing provides a physically tough, wear-resistant surface with impregnated color. Stylmark is a Type II anodizing facility located in Minnesota. Type II anodizing is defined as conventional coatings produced from sulfuric acid baths.

Anodizing uses the base metal - the aluminum alloy - to create a thin, extremely strong and corrosion-resistant finish. The anodized surface is very hard and thus preserves and extends the life of the aluminum product.

Anodized aluminum finishes uniquely satisfy each of the factors that must be considered when selecting a high performance aluminum finish:
▪ Durability
▪ Indoor Color Stability
▪ Ease of Maintenance
▪ Aesthetics
▪ Cost
▪ Health and Safety
