Ferro tungsten is the alloy of ferro and tungsten, and the proportion of tungsten and ferro is not fixed.
Definition of ferro
Ferro is an important part of ferro tungsten, which is just under the importance degree of tungsten. ferro is the chemical name of iron and its atomic number is 26. The iron is a chemical element of atomic number 26 placed in Group 8 of the periodic table. It symbolizes how faith. This transition metal is the fourth most abundant element in the crust, representing 5% and, among the metals; only the aluminum is more abundant. It is also one of the most important elements of the universe, and the core of the Earth is composed mainly of iron and nickel, generating a moving magnetic field. It has been historically very important, and a period of history called to Iron Age.(information from WIKIPEDIA)
Definition of tungsten
Tungsten is the most important composition of ferro tungsten. The Tungsten, also known as wolfram, is a chemical element with chemical symbol W and atomic number 74. It is a metal gray metal under standard conditions without ally. The tungsten is found only on Earth combined in chemical compounds. The types are the most important wolframite and Scheelite. The pure element has a strong physical characteristics, especially the fact that it is the melting point higher for all metals without ally and the second highest of all the elements after carbon. Also remarkable are its high density, 19.3 times that of water. This density is slightly higher than the uranium and 71% more than the lead. The tungsten tends to be brittle and carry small amounts of impurities, making it difficult to work. However, very pure tungsten is ductile and can be cut with a saw to bow.

Ferro tungsten is the alloy of iron and tungsten, so it shares many properties and applications of ferro and tungsten.
