What’s the difference between anodizing and hard anodizing?

Do you confuse anodizing and hard-anodizing? It’s the same thing?

Hard-anodized is thicker than standard anodized aluminum. At greater than 25 microns, hard-anodized is produced using low temperatures and higher current density to accomplish this thickness. 

A thicker surface gives hard-anodized aluminum a more abrasion-resistant surface.
