The metal with the highest melting point - tungsten
Tungsten
Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74. It is a grayish-white silvery metal found in nature only in chemical compounds. Tungsten has the highest melting point of all metals, at 3410°C (6170°F), and has remarkable corrosion ......
Tungsten in Rare High Melting Point Metals
Introduction
Tungsten is an extremely hard, rare metal that has the highest melting point of any metal found in nature at 3,422°C (6,192°F). It also has a very low thermal conductivity and an extremely high thermal expansion coefficient, making it a popular choice for use in a variety of high-t......
Production of Tungsten
Tungsten is one of the most durable and useful metals around, and its production has become a major part of the modern industrial system. Tungsten is used in a variety of applications, including medical, consumer good, automotive and technological products. In fact, tungsten is so versatile that i......
Tungsten Electron Beam Melting
Tungsten is a chemical element that is predominantly used for its high melting point and strength. It is commonly used in industrial applications, and has been used for the fabrication of semiconductors, mobile phone and computer components, radio frequency transistors, and other electrical and el......
Decomposition of tungsten concentrate
Wolframite
Wolframite is a rare mineral and an important source of the chemical element tungsten. Tungsten is used in many industrial and chemical applications, so wolframite is an important ore of tungsten. In addition to containing tungsten, wolframite is also a source of several other chemical......
Tungsten Thorium Alloy
Tungsten, also known as wolfram, is a chemical element with the chemical symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth only in chemical compounds. It is found in a few unusual minerals, but most often deposited in hot springs and as veins in rocks. It is also obt......
Niobium-titanium multi-element alloy superconducting material
NbTi Superconducting Alloys
Superconducting alloys are materials that, at very low temperatures, will conduct electricity with almost no resistance. In materials that exhibit superconductivity, a phenomenon called “zero electrical resistance” occurs. This means that a current can flow without a......
