Applications. Tungsten heater is made from Tungsten wire, which has high melting point and excellent corrosion resistance. It is mainly used as heating elements in surface vacuum coating process such as aluminum spraying, chrome-plated, mirror making, ceramic coating and plastics coating, etc.
Tungsten-rhenium wire has the features of high melting point, good toughness, good chemical stability under the non oxidizing atmosphere, less secondary pollution. Application Rhenium tungsten wire is suitable for sapphire crystal growing furnace heater binding material at 2000℃.

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. Advanced Refractory Metals is a leading supplier of Tungsten products.
The presence of chromium ensures a high melting point of oxide coating. The resistivity of Nichrome varies from 1.1 to 1.27 ohm per m and mm 2 . Nichrome is available as round wire and strip, cold drawn with an oxidized surface and also hot rolled with scale covered surface.
Tungsten is extracted from its ores in several stages. The ore is eventually converted to tungsten(VI) oxide (WO 3), which is heated with hydrogen or carbon to produce powdered tungsten. Because of tungsten's high melting point, it is not commercially feasible to cast tungsten ingots.
Tungsten wire with 3%, 5%, 25% or 26% rhenium, keeps high strength, good flexibility and mechanical properties in 2000℃ temperature. And it will not become fragile after high temperature use. Tungsten-rhenium wire has the features of high melting point, good toughness, good chemical stability under the non oxidizing atmosphere, less secondary
Tungsten's adoption is also aided by its high melting point, high density, relatively high thermal conductivity at room temperature, and low coefficient of thermal expansion . Indeed, heat flux tests have concluded that the maximum operating temperature of the helium-cooled divertor should be 800 K for the blanket first-
Tungsten wire mesh with amazing high melting point but low vapor pressure, often used for acid and hydrogen making, filtration, vacuum apparatus, heat shielding. About Us Walcoom Corp. is a professional wire mesh products manufacturer that supplies you better soultions and the quality wire meshes.
Thus, tungsten assemblies and parts are an ideal choice for users of various high temperature furnaces including hot isostatic pressing (HIP) furnace, crystal growth furnace, sintering furnace, vacuum furnace. Moreover, machining tungsten metal and alloys have been used extensively to produce furnace parts due to its very high melting point and
Our tungsten wire deserves its name due to its high creep resistance. The baskets and filaments are manufactured from high grade tungsten. Of all metals in pure form, tungsten has the highest melting point (3422°C / 6192°F), the lowest vapor pressure at temperatures above 1650°C (3000°F) and has the highest tensile strength.
Pure Tungsten is a very hard, silvery white coloured metal and has unique properties, including a melting point of 3,410 degrees Celsius (the highest of all the elements), a boiling point of 5,900 degrees Celsius, and it is one of the heaviest of all the elements.
Furnace parts and High temperature alloys. Due to high melting points and high strength, tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes, heating elements and shield in high-temperature vacuum furnaces, and turbine blades in generators and aircraft engines. X-ray targets. Tungsten is the
of the finished wire. Cutting corners early in the process to reduce wire prices can result in poor performance of the finished product. Refining tungsten from ore cannot be performed by traditional smelting since tungsten has the highest melting point of any metal. Tungsten is extracted from ore through a series of chemical reactions.
200736Sintering involves heating the tungsten part in a furnace until the compressed powder just barely starts to melt, which essentially solidifies the part, and makes it strong. Now, since tungsten's melting point is so unreasonably high, the tungsten powder used for compression forming has to be mixed with another metal that will melt during
If you want to buy tungsten wire for an application requiring very high tensile strength, unique stiffness and no spring back, a high melting point, low coefficient of thermal expansion, and low vapor pressure at elevated temperatures, you're in luck: In the form of wire, our products maintain many of tungsten's most valuable properties.
We can supply you with threaded rods, pins, washers, nuts and rivets made of molybdenum, tungsten, tantalum and niobium as well as a wide range of alloys that perfectly meet the needs of your project. And our replacement parts and tubes for the furnace construction industry offer equally high performance.
Nichrome on the other hand, although it has a pretty high melting point (1673 K) it is not as high as tungsten, but it is often used for heating devices, such as a blowdryer. An electric current can heat the filament around 2000-3300 K, which stays below the melting point of tungsten but above that of nichrome.
