Introduction


Tungsten - pure tungsten rod, pure tungsten plate, tungsten needle, RWMA Class 13,100 W, Tungsten


Tungsten has a high melting point, high temperature strength and creep resistance and thermal conductivity,

conductivity and electron emission properties are good, than the major. 

Expansion coefficient and the lowest metal vapor pressure. General use of powder metallurgy approach to 

the system.

Application:

Pure tungsten rods have special properties such as low thermal expansion and good thermal conductivity, sufficient resistance to resistivity, and high modulus of elasticity. So tungsten rods are widely used in various fields. Such as support lines, lead wires, printer needles, various electrodes and quartz stoves, filaments, high-speed tools, automotive automation products, sputtering targets


Characteristic:

Chinese "tungsten" and symbol "W" are from the German Wolfram source. Recently, it was found that the three 

most stable isotopes of tungsten are slightly radioactive.

Pure tungsten is a steel gray to tin white hard metal, very pure tungsten can be sawing sawn (pure tungsten 

is brittle and difficult to process). Tungsten processing means forging, stretching and impact. In all metals, 

tungsten has the highest melting point of 3422 ° C, the lowest vapor pressure, and the highest tensile strength 

(1650 ° C). Its corrosion resistance is very good, most of the inorganic acid on its erosion is very small. It forms 

a protective oxide on the surface of the air, but it is completely oxidized at high temperatures. Adding a small 

amount of tungsten can greatly increase the hardness of steel.


Tungsten in tungsten is a chemical element, its chemical symbol is W, its atomic number is 74, is an off-white 

transition metal. It is a very hard, steel gray to white transition metal. Containing tungsten minerals are wolframite 

and scheelite. The physical characteristics of tungsten are very strong, especially its melting point is very high, 

is the highest of all non-alloy metals. Pure tungsten is mainly used in electrical and electronic equipment, and 

many of its compounds and alloys are also used in many other applications (the most common bulb filament, 

in the X-ray tube and in tungsten is also used in high-temperature alloys).


If you want to import pure tungsten rod from one of the competitive Welding Wire manufacturers and suppliers in China, equipped with a productive factory, MAIKE is always at your service.
