tungsten over the past several years in conjunction with the development of several high temperature devices. Originally, the work was aimed at developing brazing methods for spacecraft mini-thrusters1 and rock melting drills (Subterrenes).2 Recently, however, emphasis has shifted to applications in heat-pipe cooled nu
TUNGSTEN. Tungsten is a greyish-white lustrous metal which is solid at room temperature. It has the highest melting point, lowest vapor pressure at temperatures above 1650 °C, the highest strength, and the highest hardness among all pure metals and alloys.

20191115How to Build a Metal Melting Furnace for Casting. If you want to cast metal into different shapes, you need to have a furnace that gets hot enough to melt the metal. While you can buy premade furnaces, you can also make your own using an
2300c vacuum muffle furnace high temperat vacuum nitrogen . BC FURNACE SOLUTION Beichuan is the manufacturer of high temperature vacuum and controlled atmosphere furnaces with an installed base of over 3500 units worldwide. ce 1400 degree inert gas atmosphere vacuum electric
Tungsten mesh properties: Tungsten mesh offers the highest furnace service temperature about 3000oC with suitable optical heat transfer performance for specific temperature uniformity. Large surface area decreases the watt density resulting in enhanced element service life. Mild wire tear will not affect the mesh service life in any case.
Arc Melt Furnace SA-200 is our smallest arc melt furnace and has a 2" (51mm) copper hearth which holds the sample material. The SA-200 has a single arc and arrives as a complete turn-key system that can reach temperatures above 3500°C instantly.
2002121The second important breakthrough in tungsten applications was made by W. D. Coolidge in 1903. Coolidge succeeded in preparing a ductile tungsten wire by doping tungsten oxide before reduction. The resulting metal powder was pressed, sintered and forged to thin rods. Very thin wire was then drawn from these rods.

2002121Tungsten, also known as Wolfram, lapis ponderosus or Heavy Stone, has highest melting point of all elements except carbon - sources in scientific literature vary between 3387 °C and 3422 °C. It also has also excellent high temperature mechanical properties and the lowest expansion coefficient of all metals.
Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Molybdenum properties are unique which makes it desirable for use in a number of manufacturing industries. For example, with its high melting point, 2620°C, molybdenum can work as a load bearing material in industrial furnaces at temperatures ranging 1600°C and up to 2000 °C for certain other applications.
There are a wide range of materials offered that can be utilized as heating elements for electric resistance furnaces. The materials include ceramic metal-based materials, metallic alloys and carbon or graphite materials. Certain cermets can be obtained in a wire form, a cermet being a robust alloy of a heat-resistant compound.
Tungsten. Tungsten is a rare metal that is often used as a high temperature heating element as it has a high melting point, allowing it to be used in temperatures of around 2500 o C and in high vacuum levels of less than 10-4 Torr. At lower vacuum levels of below 10-2 Toor, it can be used up to temperatures of 1200 o C. Molybdenum
Tungsten metal is known for its impressively high melting point of 3410°C (6170°F). It demonstrates low thermal expansion, low vapour pressure and good thermal conductivity - making it an ideal option for high-temperature applications.
