The main component of aluminum ingots is aluminum, which is generally between 99% and 99.9% pure. In addition to aluminum, ingots may contain traces of other elements such as silicon, iron, copper and magnesium, which to some extent affect the properties of the ingot. It is the main raw material for the production of a variety of aluminum-based products such as aluminum sheet, foil, profiles and wire. They are available in a range of sizes and weights, with common sizes including small 20 kg ingots and large 1 ton ingots. They are characterized by low density, high thermal and electrical conductivity, good corrosion resistance, good ductility and extensibility. Widely used in aluminum processing industry, construction industry, automotive industry, electrical and electronic industry, packaging industry and so on.
