Aluminium ingots are solid, high-purity (97–99%+) blocks of aluminium or alloyed material (with silicon, magnesium, etc.) used as raw material for manufacturing, automotive, construction, and aerospace industries. They are produced via smelting bauxite or recycling scrap, with grades like ADC12 and LM24 commonly used for casting, offering high strength, corrosion resistance, and versatility.
