Difference Between Anodized and Hard Anodized?

We need to know the vital differences between anodized and hard anodized cookware as it differs from the cooking experience.

Here are important facts that make anodized and hard anodized different from each other.

Anodized Hard Anodized
Anodized aluminum is thinner than hard anodized. It offers low abrasion resistance. Hard anodized aluminum is thicker than standard anodized. It enhances the abrasion resistance.
Regular anodizing is done using Sulfuric or chromic acid electrolytes. Hard anodizing is done with sulfuric acid with the combination of oxalic acid or amino sulfuric acid.
In anodized aluminum, the pores are open after anodizing. Hard anodized aluminum comes with a thick oxide layer which delivers the best wear resistance and durability.
A standard anodized aluminum offers only low to medium cooking. Even it is not safe for oven cooking. Hard anodized is best for cookware as it withstands extreme heat. The wear resistance is also very high.
