calcium
................
Metallic Calcium It is used in some alloys, for example with lead giving it greater hardness and as a reducer to extract certain metals such as thorium, vanadium, uranium and zirconium. Metallic calcium is used to remove sulfur and its compounds in the oil refining process.
nickel
................
Nickel is used as an alloying element of iron for the Manufacture of Stainless Steels.
In the iron and steel process, it improves the properties of the heat treatment by reducing the hardening temperature and distortion when tempered. In combination with chrome, it increases hardness and resistance to wear.
magnesium
................
Magnesium treatment is a necessary step in the production of nodular iron (GJS) and cast iron with vermicular graphite. Magnesium treatment of the melt serves to create nodular or vermicular graphite. These forms of graphite, when manufactured correctly, are essential in imparting the desired mechanical properties to iron.
aluminium
................
Aluminum is used in the production of Steel, acting as a deoxidizer and resulting in fine-grained steel.
