As of general concept, the induction heating involves generation of eddy currents in metals and if it is resistive enough like iron/steel, the heat is generated due to Joules effect. Since Aluminum is a good conductor, how it is heated/melted in induction furnaces?
We know for same reason Aluminum/copper cookware's are not used in induction cooktops.

Hello Akhilesh Kumar Singh,
When I was doing my technical course, we melted aluminum in a crucible, gas furnace. You need to know the principle of an induction furnace, the principle, because the electric current generated circulates through the metal itself, heating it.
Andre Felippe Vieira da Cunha plz read the full question again. It's the resistance against eddy currents heat the material. Aluminum is a good conductor, so what mechanism is involved in this case, is the question. For same reason, aluminum cookware is not used on induction cooktops. Otherwise as per your logic any type of metallic cookware can be used. Is it so??
