Anodizing: The Aluminum Extrusion Enhancement
Anodizing is an electrochemical process that fortifies aluminum’s natural oxide surface layer, rendering it exceptionally resilient and available in various translucent shades. The procedure involves thoroughly cleaning, rinsing, and etching aluminum extrusions before submersion in an acid electrolyte bath. As an electric current passes through, oxygen ions from the electrolyte bond with surface aluminum atoms, creating a robust oxide layer that resists chipping, peeling, and corrosion. This exceptional durability and color versatility make anodizing a preferred choice for architectural products, home appliances, furniture, boats, sporting goods, and personal electronics.
Performance attributes like hardness and porosity are influenced by alloy selection, the anodizing process, treatment duration, and chemistry. To address these variables, various standard anodic coating designations have been established, allowing for tailored solutions that meet precise requirements.
DURABLE ADVANTAGE
The resulting oxide layer will not chip or peel and is extremely hard and corrosion resistant, thus providing outstanding durability and low maintenance costs. Further, a number of colors can be imparted during the anodizing process. These properties lead anodizing to be a popular finishing choice for applications including architectural products, home appliances, furniture, boats, sporting goods, and personal electronics.
COATING DESIGNATIONS
Specific performance characteristics, such as hardness and porosity are dependent upon the alloy being used, the specific anodizing process and chemistry, and the length of treatment time. A number of standard anodic coating designations have been developed. These coating designations, along with a more detailed discussion of the anodizing process and variables, can be found by clicking here.
