Hardcoat or Hard Anodizing provides a surface that is harder, smoother and more wear and corrosion resistant
than standard anodizing.
Hard anodizing is usually not sealed. When the main function of the application is to obtain maximum
wear abrasion resistance.
Sealing will improve corrosion resistance.
Note: Hard Coat finishes are typically darker in appearance than standard anodizing.
