steel cooking vessel and aluminum cookware will not work for induction cooking.
which two types of cookware will not work for induction cooking?
steel cooking vessel
aluminum or copper alone does not work on an induction stove because of the materials’ magnetic and electrical properties. aluminum and copper cookware are more conductive than steel, but the skin depth in these materials is larger since they are non-magnetic. the current flows in a thicker layer in the metal, encounters less resistance and so produces less heat. the induction cooker will not work efficiently with such pots. however, aluminum and copper are desirable in cookware, since they conduct heat better. because of this 'tri-ply' pans often have an induction-compatible skin of stainless steel containing a layer of thermally conductive aluminum.

induction compatible cookware for an induction cooking surface can nearly always be used on other stoves. some cookware or packaging is marked with symbols to indicate compatibility with induction, gas, or electric heat. induction cooking surfaces work well with any pans with a high ferrous metal content at the base. cast iron pans and any black metal or iron pans will work on an induction cooking surface. stainless steel pans will work on an induction cooking surface if the base of the pan is a magnetic grade of stainless steel. if a magnet sticks well to the sole of the pan, it will work on an induction cooking surface. an "all-metal" cooker will work with non-ferrous cookware, but available models are limited.
