Introduction
Ferrotitanium is a ferroalloy composed of titanium and iron, with occasional trace carbon. It was first discovered in 1798 by W. Gregor and was partially purified by H. Moissan in 1895.
It can be obtained by melting scrap titanium together with steel or iron in an induction furnace. The alloy is highly reactive with nitrogen, oxygen, carbon and sulfur, forming insoluble compounds. It has low density, high strength and excellent corrosion resistance.
The following section will discuss ferrotitanium in more detail.
