Because there is no absolutely non-magnetic permeability material, aluminum, copper and stainless steel can be heated (our company has stainless steel bright aging equipment, copper tube online annealing equipment, non-ferrous metal heating equipment, because it is not for advertising, do not say the company name). Aluminum heating is no problem, but the thickness of the "foil" affects the efficiency, because induction heating is the role of magnetism in the metal, too thin, its magnetic flux is too small, and too easy to dissipate heat, except for hundreds of you can license to do multiple superposition. Recently, I pushed off several large projects for thin plate heating (all with a planned investment of more than two million), and suggested that they choose conductive heating.
