An electronic appliance is worthless unless electricity powers it, an automobile won’t budge unless we fill its tank with fuel. Similarly, a human body requires food to prosper in its metabolism process and grow. Food for a living being is the fuel which enables us to do our daily work. But this food could turn out to be worthless if it isn’t cooked using proper means. Before choosing any suitable means, one must target the proper container to cook the food in. Selecting an appropriate container for one’s food is as important as choosing an appropriate ingredient for one’s recipe.

The cookware we use may often get subjected to setbacks like rust, toxicity and other damages. To protect our cookware and ourselves from harmful diseases, various technologies have been developed which we can use to secure the process of cooking. Anodizing is one such method.

Anodizing is a method developed by chemists to increase the corrosion resistive power of metal by forming a layer of oxide on its surface. Hard anodized cookware is widely preferred all around the world due to their durability and reliability.


The majority of cookware present in our kitchen cupboards consist of aluminum. Due to its lighter weight and non-conductivity, aluminum has been preferred over steel in the market for a very long time. Aluminum is made stronger through the process of anodizing. The scientific process of anodizing involves immersing aluminum in a bath of sulfuric acid which acts as an electrolyte. An electric current of low voltage is passed through the acid solution. This process forms a thin coat of aluminum oxide on the surface of the aluminum sheet. On cooling to the freezing point of water, the amount of electricity is increased subsequently. This chemical process is known as hard anodizing.

Some aluminum cookware may undergo the process of hard anodizing. Hard anodizing has advantages of its own. It produces a much thicker coating of aluminum oxide which penetrates the holes as well as fissures in the surface to result in a uniform appearance. As a result, hard anodized cookware is better than the regular anodized aluminum. Aluminum sheets processed using hard anodizing have a brown or black surface, but other colors can be created.

Hard anodized aluminum is a better option as compared to stainless steel. Manufacturing hard anodized aluminum is much easier than penetrating a similar block of stainless steel. These products are also resistant to harsh weather, salt sprays, and nother abrasive machining processes. It is also said to be so hard that it may walk toe to toe with diamond.

Applications of hard anodizing can be widely seen in the automobile industry and the commercial cookware industry.

Nonstick coatings like Teflon must possess a reliable method to create a strong adhesive bond. Hard anodizing can incorporate Teflon during the electrolytic process. When shopping for cookware, one must read the label carefully to find out if the product is an ‘anodized aluminum’ one or a ‘hard anodized one.’ The cookware marked ‘hard anodized’ has more durability, but it is expensive.


  • HARDNESS: The best thing about anodized cookware is its durability. This cookware is scratch resistance and hence could be considered twice as hard as stainless steel. It won’t be an exaggeration if we assume anodized products to be 80% harder than traditional raw materials through the strength of each product depends extensively on the anodizing process

  • NON-TOXIC: Unlike many other traditional raw materials, anodizing a metal eliminates all the possibilities of toxicity. Teflon was once a major preference for manufacturing of cookware, but traces of toxicity led to its downfall. Anodized cookware possesses a smooth surface by virtue of the electrochemical anodized process which makes it non-toxic as well as non-stick.

  • NON REACTIVE: Anodized cookware is non-porous thus acidic food like tomato sauces, and lemon juices won’t have the chance to settle into pores and cause unstable chemical reactions. Hence, using anodized products safeguards the quality of the food.

  • BETTER COOKING PERFORMANCE: Due to its various advantages over other products, this technique provides an overall better experience. Anodizing an aluminum cookware conducts heat faster as well as uniformly.

  • EASY MAINTENANCE: Since these products are nonporous, nonstick and hard, cleaning them is an easy task. Hard anodized cookware can be used for a prolonged period of time due to the collective perks.

It is always better to buy a single strong product rather than buying ten weak products. Hence, a single hard anodized cookware may be expensive, but it serves a great purpose as compared to ten other inferiorly built cookware. They are not only constructed elegantly but also possess a robust quality. Due, to all these properties, hard anodized cookware has been gaining huge popularity lately.
