ADC12 Die Casting Automobile Anodizing Chassis Parts

Anodizing cannot peel off as the coating is actually part of the metal. Anodizing gives aluminum alloy a deeper, richer metallic appearance than otherwise possible. Further, computerized color matching with quantitative, objective color data is possible now. Anodizing is the ideal method for today environmental concerns. Though more research needs to be done to determine the total environmental impact of different aluminum finishes, it is evident that anodizing does far less damage. 
 Anodizing which is improperly sealed has poor chemical resistance. Brand new anodizing with a thin coating thickness is nearly identical in appearance to an Aluminum Association Class I anodized finish. Very thin anodized coatings are unsuitable for use on exterior curtain wall or metal roofing. 

The one distinct advantage of a thicker anodic coating is its durability and longer life. It must be noted that anodized surfaces, like other building components, must be protected from acidic attack during construction activity.
