About Ferro Tungsten
Ferro Tungsten is an alloy formed by combining Iron and Tungsten with a Tungsten content range in two grades (A and B) of 75%-82% and 70%-75% respectively. Ferro Tungsten is a remarkably robust alloy because of its high melting point. In fact, Tungsten has the second highest melting point after Carbon. By combining Iron with Tungsten, the relative brittleness of Tungsten in its pure form are overcome thus Ferro Tungsten is often a major component of popular super alloys.
Key Properties of Ferro Tungsten
Ferro Tungsten as an additive to the production process of ferrous metals will impart several desirable properties upon the new alloy. One of the primary benefits of adding Ferro Tungsten to an alloy is to increase the alloy’s melting point, making it suitable for aerospace applications as well as welding applications. Additionally, by adding Ferro Tungsten to an alloy, one can take advantage of Tungsten’s unique electrical capabilities as a conductor. For example, Tungsten is used in field emission guns like electron microscopes and in IC chips, as well as metallic films that can replace conventional copper wiring.
Production of Ferro Tungsten
Tungsten is found in the minerals Wolframite, Scheelite, Ferberite and Hubnerite. The minerals are mined and converted to Tungsten oxide and then heated with Hydrogen or Carbon to produce a powdered form that is mixed with Iron.
A good example of Ferro Tungsten usage is in high-speed steel, which may contain as much as 18% pure Tungsten. These super alloys are used in the production of turbine blades and other wear-resistant coatings and parts. Other applications requiring the high density of Ferro Tungsten alloys are heat sinks, counter weights, ballast keels, commercial aircraft tail ballast, and NASCAR and Formula 1 car ballast. In armaments, Ferro Tungsten is used in kinetic energy penetrators as an alternative to depleted uranium, but is also used in projectiles and grenades to create super-sonic shrapnel. Ferro Tungsten is also used in the manufacture of game darts for the popular bar game (the Ferro Tungsten creates darts yielding smaller diameters, thus tighter groupings during play). Ferro Tungsten is also found in fishing lures (as the Ferro Tungsten alloy beads sink rapidly).
