SCHAUMBURG, IL – The American Architectural Manufacturers Association (AAMA) has released an updated document laying out the anodizing process with reference to architectural work. According to AAMA, this standard describes the anodizing process, which produces a coating that is thicker than nature's version, harder and very durable. The AAMA Anodic Finishes/Painted Aluminum (AFPA) document has been updated to reflect newer technologies now available for the process involved.
The appearance and physical properties of anodic finishes are discussed as governed by three factors, which are aluminum alloy and temper, surface treatment prior to anodizing, and the type of electrolyte and operating techniques used in the anodizing process.
