Description

1. Manufacturing Process: Aluminum ingots are typically produced through the smelting and casting process. Bauxite ore, which is the primary source of aluminum, is refined into alumina (aluminum oxide) through the Bayer process. The alumina is then electrolyzed in a smelter to obtain molten aluminum, which is poured into molds or “ingot molds” to cool and solidify.
2. Purity and Alloy Composition: Aluminum ingots can vary in purity and alloy composition depending on their intended use. Primary aluminum ingots are typically high-purity aluminum (often 99.7% purity or higher) and are commonly referred to as “virgin” or “primary” ingots. Alloying elements can be added during the smelting process to create specific aluminum alloys with desired properties.
