What is FeTi70

Ferrotitanium (FeTi) is an alloy of titanium (Ti) and iron (Fe).

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.

Depending on the brand, the titanium content can vary from 20 to 75%

20-25% Ti is meant to be used in foundries
35-40% Ti for welding
70% Ti for Stainless Steel production
