Product Description Tungsten Rods 1.Molecular formula: W2.Molecular weight: 183.843.Storage: Store in a cool, dry place.Tungsten is a nonferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. In 1781, Swedish chemist Carl William Scheyer discovered scheelite and extracted a new element acid - tungstic acid. In 1783, the Spanish man De Pulya discovered that wolframite also extracted tungstic acid from scheelite. In the same year, tungsten powder was first obtained by reducing tungsten trioxide with carbon, and the element was named. The content of tungsten in the crust is 0.001%. 20 kinds of tungsten minerals have been found. Tungsten deposits are generally formed with the activity of granitic magma. After smelting, tungsten is a silvery white and shiny metal with a very high melting point and hardness. Atomic number 74. The steel is gray or silver white, with high hardness and melting point, and is not subject to air erosion at room temperature; It is mainly used to manufacture filament and high-speed cutting alloy steel, superhard mold, and also used in optical instruments and chemical instruments [tungsten; wolfram] -- the wire drawn from the element symbol W. Tungsten rod, which can be used as the filament in electric bulbs, electronic tubes, etc.Purity99.92%min CAS7440-33-7EINECS 231-143-9 Forging rodФ2.4~95mm Straightening rod (after drawing) Ф0.8 ~3.2mmMFW Applications1.Semiconductor ion implantation parts2.Electric light source and electric vacuum part3.Refractory parts of industrial high temperature furnace4.Electrode for argon arc welding and resistance welding Related Products Chromium granule Iron based alloy powder Q: Are you trading company or manufacturer ?A: We are factory.Q: How long is your delivery time?A: Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.Q: Do you provide samples ? is it free or extra ?A: Yes, we could offer the sample for free charge but do not pay the cost of freight.Q: What is your terms of payment ?A: Payment<=1000USD, 100% in advance.
