Steelo Fabrica is a great exporter, manufacturer, and dealer of Tungsten class 2, class 3, class 4 Round Bars. We use national and international standards to manufacture these round bars. There are different specifications of these round bars like different lengths, sizes, surface finish, and widths. These tungsten class 3 round bars offer different surface finish like black surface finish, cleaned surface finish, and Shiny surface finish.
What is Tungsten Class 2 round bar?
Our company manufacture these round bars are available in different sizes, lengths and widths. Due to tungsten class 2 alloy, our round bars have a high melting point and density. Our round bar has different surfaces like a Sintering surface, Forged surface and ground surface and polished surface. It also shows resistance to creep and high temperature. Our round bar shows resistance to attack by most mineral acids. Our round bars have high tensile strength.

What is Tungsten alloy?
Tungsten alloy is made up of using tungsten, iron, copper, nickel, cobalt and molybdenum. It contains cobalt to increase strength and ductility. This metal is very affordable. There are four classes of tungsten such as class 1, class 2, class 3 and class 4. Class 2 has low density than other classes of tungsten. Class 3 has a high density that is easier to produce and machine relative to pure tungsten. It is often used for x-rays, radiation, and other medical shielding applications. This tungsten Class 4 shows high density and high tensile strength. This alloy is very easy to machine and produce. The benefit of tungsten is its extremely low vapor pressure, even at high temperatures.
Properties of Tungsten Class 3 round bars:
Tungsten class 3 round bars have many special properties such as wear resistance, high tensile strength, good elongation capacity, low vapour pressure, excellent thermal stability and high radiation absorption capacity, etc.
