Manufacturing
Primary aluminium can be rolled, extruded or cast to meke aluminium end-products. Rolling involves a block of aluminium being 'squashed' between large rollers to make products such as aluminium plates, sheets or foil.
Extruding is a process in which round logs (billet) of hot aluminium are forced though a pattern cut into steel die. Casting occurs when molten aluminium is poured into moulds to manufacture specific shapes.
