This blogging site provides professional knowledge of tungsten, molybdenum, tantalum, columbium to expand the markets for refractory metals.
What is the Most Refractory Metal in the World? In the non-ferrous metal family, tungsten has maintained the title of “High-Temperature Champion” for hundreds of years. The first person in the world to discover tungsten was the Swedish chemist Seler. He first decomposed tungstic acid with acid in 1781 to obtain tungsten. Then, after a […]

Tungsten 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, which has been widely […]

The quality parameters of tungsten powder are powder size and purity. Although the essence of the growth of tungsten particles is the volatile deposition during the reduction process, there are many influencing factors, including raw materials, hydrogen flow rate and technological conditions. Raw material In the preparation of ultrafine tungsten powder, the selection of powder […]
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 […]
3D printing is also known as additive manufacturing. Similar to the powder metallurgy processes we use today, metal devices manufactured with this technology are based on metal powders, such as ceramic powders and metal powders. The difference is that the powder is not sintered together, but formed by “printing” sections of the parts onto the […]

Technology is an essential cornerstone of modern weapons research and development. But in terms of importance, mineral resources are still above technology, which is because technology can be developed while it is really nothing can be done without materials. What are the top five strategic metals in the world? Titanium One metal known for its […]

Can you imagine 80 kilograms of discarded products with batteries or plugs piling up in your living room? That’s how much e-waste the average American household throws away each year. The latest data from the 2017 global e-waste monitor report, released by the United Nations University (UNU), the International Telecommunication Union, and the International Solid […]

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 […]
