WebMolten aluminium is siphoned from the bottom of the cell by a process called tapping. The aluminium is then transported to a holding furnace to be cast into products. Casting takes place in temperatures of just over 700°C. Aluminium is cast into ingots, large blocks, t-bars or long cylindrical logs called extrusion billets. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al 3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency.
