TUNGSTEN ALLOY CRANKSHAFT

Tungsten is a chemical element with atomic number 74 and W is the chemical symbol of it which stands for wolfram. The name of "tungsten" means "heavy stone" in some countries .Tungsten is much harder than Gold and steel, otherwise, it is great cheaper than gold. It is a grayish-white lustrous metal in raw form and often brittle and hard to work, however, if it is in the form of pure, it can be worked easily. Pure tungsten is mainly used in electrical applications, while tungsten compounds and alloys are usually used in various applications such as in incandescent light bulb filaments, X-ray tubes, super alloys and so on... Tungsten alloy is consisting of W and some additives usually Fe,cu or other elements. Tungsten alloy famous for their high density ranging from 16.5 to 18.5 owing to the normal content of W in tungsten alloy is from 90 to 95 percent.Tungsten alloy generally is refractory metal and have two-phase composites such as the combination of W-Ni- Fe or W-Ni- Cu or even W..
