No, hard-anodized cookware is generally not suitable for use on induction cooktops. Induction cooktops work by creating an electromagnetic field that directly heats the cookware, and for this to happen, the cookware must be made from a magnetic material. Unfortunately, hard-anodized aluminum is not magnetic, which means it won't work on induction cooktops.
Hard-anodized cookware is made by subjecting aluminum to an electrochemical process that creates a hard, nonstick surface. While it's durable and provides excellent cooking performance, it lacks the magnetic properties required for induction cooking.
For induction cooktops, you need to use cookware that is specifically labeled as "induction compatible" or "induction-ready." This type of cookware is made from magnetic materials, such as cast iron or magnetic stainless steel, which can interact with the induction cooktop's magnetic field and generate the necessary heat for cooking.
If you want to use induction cooktops and still enjoy the benefits of hard-anodized cookware, some manufacturers offer hybrid cookware that combines hard-anodized aluminum with a magnetic stainless steel base. This base allows the cookware to work on induction cooktops while still retaining the advantages of hard-anodized surfaces. Look for cookware labeled as "induction compatible" or "induction-ready" to ensure it will work on your induction cooktop.
