Cuisinart offers four cookware types: aluminum, hard-anodized aluminum, stainless steel, and copper. Stainless steel cookware is either fully-clad or single-ply with an encapsulated (cladded or impact-bonded) base to improve cooking performance and heat distribution. The copper offerings are fully-clad with a copper exterior, aluminum core, and steel cooking surface. The non-stick surfaces are coated with either a PTFE-based or ceramic material. You can learn about the differences between these materials in my in-depth guide to the best cookware materials.
