Anolon, the American gourmet kitchenware line, makes its dishwasher-safe cookware from hard anodized aluminum. It also integrates the aluminum with a layer of stainless steel, bronze or copper to increase durability or improve conductivity.
Hard anodized aluminum cookware is a safe choice, as the anodizing process seals in the aluminum and prevents it from leaching into food and posing a health hazard, even with foods that are acidic. Its advantages include a lightweight, nonstick surface that is resistant to rust and corrosion and conducts heat evenly. The company offers the cookware in collections such as the Anolon Advanced Bronze and Nouvelle Copper.
