ferrotitanium

[¦fe·rō·tī′tān·ē·əm]
(metallurgy)
A ferroalloy containing 15-45% titanium and used in steelmaking.

Ferrotitanium

 

a ferroalloy consisting of up to 35 or more than 60 percent Ti, 1–7 percent Al, 1–4.5 percent Si, and up to 3 percent Cu (Fe and impurities accounting for the remainder). The ferrotitanium with the lower percentages of Ti is produced by the nonfurnace aluminothermic method from ilmenite concentrate and titanium tailings; the higher percentage type is obtained by smelting iron and titanium tailings in an electric furnace. Ferrotitanium is used in deoxidizing and alloying steel.
