This involves immersing the aluminum in a chemical bath and applying an electrical current to it, causing oxide to be produced from the resulting rust on the aluminum. This layer of oxide hardens the aluminum and makes it resistant to corrosion.
'Hard anodized' is an extension of the process using higher voltage and lower temperature, which results in an even harder and more durable (cookware) coating.
Anodized aluminum has many applications, including consumer products and industrial building materials. Because color can be applied to the oxide due to its porous nature, this durable, corrosion-resistant and lightweight material is also used in the manufacture of electronic equipment. Cookware or bakeware that is hard anodized is assumed to have a much more durable cooking surface than some other nonstick finishes.
The cooking equipment featured is Cuisinart's Hard Anodized Cookware 11-pc set. The aluminum construction improves performance with even and quick heating. Hard anodizing this aluminum coating gives it durability and a nonstick finish for ease of use and cleaning. The anodized process keeps the pan weight comfortable. Compare prices

Even though hard anodized cookware has a more durable finish, it should be properly stored to prevent scratches in the finish or dents in the pans. There are various ways to store cookware including using a pot rack, designating a cabinet space or using in-cabinet slide-out racks.

Anodized aluminum is often used in the making of cookware, because it provides a very durable non-stick coating which is resistant to corrosion and salts, and has excellent heating and cooking abilities.
