Tungsten also referred to as Wolfram, is a chemical element with the chemical symbol W and atomic number 74. After Carbon, Tungsten has the highest melting point of all elements. Tungsten is among the heaviest metals found on Earth. It has excellent high-temperature mechanical properties, with the lowest expansion coefficient and highest conductivity of all metals.

When it comes to the world’s highest melting point or the most refractory material, many people jump the gun and say “Tungsten.” But I want to tell you that this answer is only half true. As we all know, tungsten is a pure metal with the highest melting point in the world, but the most […]
Tungsten alloy counterweights (tungsten counterbalances, tungsten balance weights) are made from tungsten heavy alloy. They help to reduce the loads that parts are exposed to and consequently increase their service life, which are crucial components in many different applications. Development history Tungsten alloy counterweight has a long history. China has entered the heyday of bronze […]
Tungsten, which has an atomic number of 74 in the periodic table, is a VIB group metal. It has a density of 19.35 g/cm3 that is close to gold, with a melting point of 3,422 ℃ and a boiling point of 5,927 ℃. Tungsten is a silver-white, steel-like metal with the highest melting point of […]
If tungsten runs out and only a short mining life remains, what will support the vibration of the iPhone? “A perfect storm may be brewing because supply is shrinking fast”, says a professor of sustainability at the Rochester Institute of Technology. So, what is this storm about? And what supply is about to “shrink”? Why […]
A tungsten alloy, also known as a high-specific tungsten alloy, is a refractory metal consisting of W-Ni-Fe, W-Ni-Cu, and W-Ni-Cu-Fe. Tungsten alloys have high melting points and are twice as dense as steel and 50 percent higher than lead. Currently, WNiFe is a popular ingredient for high-specific tungsten alloys, such as W-Ni-Fe Alloy, which can […]
In nature, platinum group elements together with gold and silver are known as precious metal elements. Platinum family has platinum, iridium, rhodium, and palladium. The most important value of platinum is not that it is a platinum jewelry, but that it is an important industrial catalyst, such as in the aerospace fuel and new energy […]
Tungsten is the most plentiful of the refractory metals. However, about half of the world’s reserves are found in China. Korea is another important source along with Bolivia, Portugal, Australia, Thailand, Canada and United States. Despite its resources, the United States still must import most of its consumption. Since the late 70’s the use of […]
Tungsten (W) is one of the so-called transition metals with the atomic number 74. The shiny gray metal is in a solid state at room temperature. Tungsten is characterized by special physical and chemical properties: Heat resistance: After carbon, tungsten has the highest melting point of all elements of 3422°C. It has a boiling point […]
Tungsten is a metal element with atomic number 74 and atomic weight 183.84. It’s usually steel gray or silver white with high hardness and high melting point. It has air corrosion resistance at room temperature. The main application of tungsten is manufacturing filament, high-speed cutting alloy steel, and super-hard mold. Besides, tungsten is also […]
