| Calphalon Cookware was originally used by chefs in their restaurant kitchens. It's a heritage they are proud to claim and one that continues to be seen in the products they offer for the home chef. In the late 1960s, the company adapted an electrochemical process used in the aerospace and architectural industries to harden raw aluminum. The process, called hard-anodizing, causes the aluminum to develop a hardened surface that is 30% harder than stainless steel. The company produced the first hard-anodized professional-quality cookware to be marketed successfully to the consumer. Originally the Commercial Aluminum Cookware Company, it was renamed Calphalon in 1997, and is now a wholly owned subsidiary of the Illinois-based Newell Company. |
