Wheatstone is a coated pan. Maifanshi pot does not mean the pot material is Maifanshi, but the surface of the Maifanshi pattern coating of aluminum alloy pot. The main material of Maifanshi pot is aluminum alloy, and there is a special coating on the surface of the pot, which uses a special process to fuse the Maifanshi material on the aluminum alloy substrate, so that the surface of the pot has a Maifanshi pattern and color. This coating is not only beautiful, but also has a variety of functions, such as speeding up the heat conduction, extending the life of the pot, and making the meals cleaner and more hygienic. At the same time, Maifanshi is a natural silicate mineral, non-toxic and harmless, and has certain biological activity. Its main chemical composition is inorganic silica-aluminate, including SiO2, Al2O3 and other oxides, and also contains a variety of macronutrients and trace elements needed by animals. Therefore, these elements will have certain benefits to human health during the use of Maifanshi coated pots and pans.
