Aluminum ingot production is composed of bauxite mining, alumina production, aluminum electrolysis and other production links. First, bauxite is mined, then aluminum ore powder is produced through water washing, grinding and other processes, and then aluminum oxide is obtained through four complex processes, including roasting.

Aluminum alloy ingots are made of pure aluminum and recycled aluminum as raw materials, and other elements, such as silicon (Si), copper (Cu), magnesium (Mg), iron (Fe), are added according to international standards or special requirements to improve the casting, chemical and physical properties of pure aluminum.
