Due to chemicals used in the process, anodizing offers a very limited color selection while Cerakote offers over 200 unique colors. Unlike anodizing that is known for its drastic color inconsistencies, Cerakote colors are held to a consistency standard of a Delta E of 1 or less. Cerakote does NOT detrimentally impact the fatigue properties of aluminum alloys while anodizing creates a brittle and porous oxide layer and tensile residual stress. Environmentally, Cerakote does not contain any heavy metals and is VOC exempt in all 50 US states. Some anodizing processes release hexavalent chromium, which is a powerful carcinogen, into the environment.
