Aluminium Wire Rod Value Chain

Aluminium is the third-most abundant element in the earth's crust. It is found in different types of minerals. Bauxite is the primary raw material for refining aluminium oxide, or alumina, which is used to produce primary aluminium metal. Bauxite deposits are mainly found in a wide belt around the Equator.

The raw material required for the production of primary aluminium is aluminium oxide, or alumina, a white powder refined from bauxite. To produce one tonne of aluminium in an electrolytic reduction process requires approximately two tonnes of alumina.

The aluminium electrolytic process requires electric energy, about 13 kWh per kilo aluminium produced in modern production lines. Energy accounts for roughly a third of the cost of production of aluminium. Therefore, an important factor is long-term supplies of energy at affordable prices.

Pure aluminium is made from the alumina by a process carried out in electrolytic cells, where a carbon cathode placed in the bottom of the cells acts as an electrode. The anodes, also made of carbon, are consumed during the electrolytic process when the anode reacts with the oxygen in the alumina. Molten aluminium is tapped from the cells.

Molten aluminium is tapped from the pots and cast into logs, rolling slabs or ingots, depending on whether further processing is extruding, rolling or remelting. Small quantities of other metals can be added to the liquid aluminium to produce foundry alloys of different durability and tensile strengths.

Aluminium is ductile. Foil can be rolled to only 0.007 mm thickness, but will still be completely impermeable and lets neither light, aroma nor taste substances in or out. The metal itself forms a protective oxide coating and is highly corrosion resistant. Different types of surface treatment can further improve these properties.

Aluminium ingot is heated and pressed through shaping tools, to make profiles for various products. Aluminium is increasingly taking over from copper as preferred metal for tubing in heat exchangers and air conditioners. There is no end to what shapes aluminium end products can take.

Windows, car parts, doors, tubes, façade panels, cans… Hydro is the industry leader in many product areas for aluminium, especially in transport, buildings, packaging and lithographic plates. And in the end, the used product can be recycled – again and again.


Wire diameters: 6.5 /7.5 /9.5 /19.0 mm Coil weight: 2000 /3000 kg

Coil diameters: Maximum 1450 /1660 mm Minimum Aluminium: 99.7 %

Rolling mill

We have integrated our manufacturing process by installing a state-of-the-art rolling mill to manufacture in-house EC (Electrical Grade) rod from aluminium ingots. With purity of 99.7% of aluminium (higher than others) in EC rod, this property maximizes the conductivity and makes this rod excellent for use in ACSR conductor.
