The production of aluminium wire rod from raw bauxite ore involves two primary industrial processes: the Bayer process and the Hall-Héroult process.

Here’s a step-by-step breakdown:

1. Bayer Process: Bauxite ore is refined to extract alumina (aluminium oxide, Al₂O₃). The ore is digested in a hot sodium hydroxide solution, which dissolves the aluminium content. Impurities (like iron oxides) are filtered out as “red mud,” and pure alumina is precipitated and calcined.
2. Hall-Héroult Process: The purified alumina is dissolved in molten cryolite and subjected to electrolysis in a carbon-lined cell. A powerful electric current is passed through the solution, reducing the aluminium ions to molten metallic aluminium, which settles at the bottom of the cell and is tapped off periodically.
3. Continuous Casting & Rolling: The molten aluminium is cast into large ingots or directly fed into a rolling mill to form wire rod. For electrical-grade rods like 1350, strict controls ensure high purity and uniform grain structure.
4. Wire Drawing: The rod is then drawn through dies to reduce its diameter for specific wire applications, maintaining its conductivity and mechanical integrity.

This entire process transforms raw bauxite into high-purity aluminium wire rod suitable for electrical and industrial uses.

While aluminium 1350 is primarily known for its electrical applications, its unique combination of physical and electrical properties also makes it valuable in aerospace, defence, and advanced industrial systems.
