Advantages of aluminum wok:
1. Aluminum wok is light, durable, fast heating, uniform heat conduction, and rust free. Aluminum products mainly include refined aluminum (soft aluminum) products and cast aluminum (hard aluminum) products. The materials are aluminum and aluminum alloy.
2. The surface color can be divided into white, light yellow and other colors. The white aluminum products are divided into casting and stamping. After turning and mechanical polishing, the surface of the cast aluminum products is white, but the metal structure is loose and there are some casting defects. Stamped aluminum products, the surface of which has been whitened, sanded and mechanically polished, have a natural oxide film with a film thickness of only 0.01-0.15 μ m. Thin and uneven, easy to be scratched or worn by machinery. The yellow aluminum products are stamped products that have been anodized to form a layer of light yellow artificial oxide film on their surface. The oxide film is generally 5-20 thick μ m. Uniform and dense, the membrane will not be damaged in 100 seconds under the action of strong alkali. Therefore, light yellow aluminum products are the best. They are beautiful, easy to remove dirt, strong in corrosion resistance and wear resistance.
