What is Hard-Anodized Aluminum Cookware
Hard-anodized or infused-anodized aluminum is a new type of nonstick cookware, and has become very popular for superior features among other nonstick gear ‐harder, lighter, better heat distribution, easier to clean and safer than those old paths. Do not surprise why this cookware is staying in the best-selling ranks these days.
Anodized is an electrochemical process of increasing the thickness of the natural oxide layers of surfaces of aluminum alloy. Base on MIL-A-8625 standard, hard coat must be thicker than 1.0 to 5.0 mm, as well as normally has Rockwell “C” hardness ranging from 50 to 70. The coating type outstandingly features scratch, rubbing and abrasive resistance. The theoretical procedure starts with dipping the metal (aluminum) pots and pans into sulfuric acid tube while giving electrical charge, the result is the aluminum oxide, which is combination of aluminum and oxygen, will occur with the surfaces of the cookware, which make become extremely hard and nonreactive finishes. Say, this kind of material is twice the strength of stainless steel.
Initially, hard-anodized cookware was made for commercial or restaurant uses. Then it becomes admired by consumers who prefer professional quality in both performance and construction. As the result, there’re wide ranges of infused aluminum pots and pans from low price to high-end in the market.
