What Is Anodized Coated Aluminum?

Andonized Aluminum

Anodized coated aluminum is commonly used as efficient, modern cookware that evenly distributes heat while cooking. Anodized products are not applied with a coating, but rather put through an electrochemical conversion process that produces anodization.

What Does "Anodized" Mean?

Chemical Process

"Anodized" refers to a process that converts aluminum to its oxide. To be precise, aluminum is placed in an acid solution and exposed to an electric current, where a layer of aluminum oxide is deposited on the aluminum surface. This process is called anodization.

Uses for Anodized Aluminum

Construction Uses

Anodized aluminum is used for architectural structures, appliances, building materials, boats, food preparation equipment, automobile parts, sporting goods, jewelry and art.

Features of Andonized Aluminum

Hardness of Diamonds

Andonized coated aluminum has the hardness of a diamond, and is sometimes referred to as "hard anodized" aluminum. Anodization creates abrasion and corrosion resistance.

Do it Yourself

Andonize Aluminum Objects

With education and preparation, it is possible to andonize items at home. Paint ball guns (guns that shoot round plastic coated balls of water soluble paint) can be andonized (see Resources), in addition to other aluminum objects like bicycle parts. Anodizing aluminum parts adds durability and can change the appearance of ordinary parts, even adding color to them.

Care and Cleaning

Wash in Warm Soapy Water

Anodized coated aluminum should be washed in warm, soapy water. Dishwashers are not recommended for anodized cookware.
