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 […]
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 […]
Tungsten is the most heat-resistant metal, and it has the highest density and strength of refractory metals. Tungsten alloys with alloying elements have good wear resistance, corrosion resistance, electrical conductivity, and thermal conductivity. The mechanism design and safety performance of aerospace equipment are closely related to the physical, chemical and mechanical properties of the materials […]
Refractory metal materials mainly refer to tungsten, molybdenum, tantalum, niobium, rhenium, and vanadium, all of which are materials with a melting point above 2000 degrees Celsius. Refractory metal materials and their alloys have the characteristics of high melting point, high strength under a high-temperature environment, strong corrosion resistance to liquid metal and processing plasticity. Refractory […]
Refractory materials, such as refractory metals, alloys, compounds, and composites, have always been developed as high-tech materials due to their unique high melting point and some other unique properties and occupy an important position in the national economy. For example, cemented carbide with WC as the hard phase has become the “Tooth” of modern industry, […]
Space, once the arena of great power rivalry, now depends on international co-operation for its costly endeavor. The aerospace industry represents the economic, military and technological level of a country, and is also an important symbol of a country’s comprehensive national strength and national defense strength. Of course, the development of the aerospace industry requires […]
