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.
General Application:
A resistance welding machine electrode, a sputtering target, a counterweight, and a heating element.
Specifications: plate, round bar. According to the drawings to provide a variety of tungsten processed products. ??
Chemical composition: tungsten> 99.95%
Physical properties:
Density: 19.3 g / cm3
Melting point (liquid): 3422 ° C
Conductivity: 30% IACS Min
Hardness: 69HRA Min.
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.
