Anodized aluminium or ‘hard anodized’ cookware has become a popular choice for the enthusiastic home cook and professional chef alike.

So what is anodized aluminium? Essentially anodized aluminium is aluminium hardened by an electro-chemical process. This process involves submerging aluminium into acid and then electrically charging the metal to oxidise the cookware’s surface.

Benefits of Hard Anodized Cookware

The oxidisation process that results in the anodized aluminium surface creates numerous cooking benefits:

  • Hardness and Durability – The anodized aluminium surface is twice as hard as stainless steel. Durability is outstanding due to the toughness of the surface, making the cookware resistant to chips, peeling and corrosion. Also due to the tough surface no chemical reaction will occur between food and the hard anodized cookware, standing up to acidic foods like tomatoes.

  • Lightness – Despite being twice as hard as stainless steel, anodized aluminium retains the lightness of regular aluminium cookware, making pots and pans easy to carry/move around the kitchen.

  • Excellent Heat Conductivity and Even Cooking – Under the hard anodized surface remains an aluminium core that provides excellent heat conductivity and distribution, creating even cooking and eliminates hot spots.

  • Professional and Attractive Look – The handsome dark finish of hard anodized aluminium makes the cookware attractive and generates a feeling of buying professional quality.

Hard Anodized Use and Care

Unless stated otherwise, wash hard anodized cookware by hand. Dishwasher detergent and soaps can discolour the cookware’s surface.
