احصل على السعرPure iron is highly ductile, and therefore, unsuitable for certain applications where a lot of tension is involved. When carbon and other elemental inclusions such tungsten, chromium, etc., are made to pure iron, they act as a toughening agent, solidifying its crystalline lattice structure and preventing the dislocations of iron atoms.

احصل على السعرThe aluminium production process can be broken down into three stages; first bauxites, which contain aluminium, are extracted from the ground. Second, bauxites are processed into alumina or aluminium oxide, and finally in stage three, pure aluminium is produced using electrolytic reduction, a process in which aluminium oxide is broken down into its components using electric current.
