Tungsten Is Mainly Used In The Production Of Hard Materials Based On Tungsten Carbide, One Of The Hardest Carbides, With A Melting Point Of 2770 °C. Wc Is An Efficient Electrical Conductor, But W2c Is Less So. Wc Is Used To Make Wear-Resistant Abrasives, And "Carbide" Cutting Tools Such As Knives, Drills, Circular, Mining And Turning Tools Used By The Metalworking, Woodworking, Mining, Petroleum And Construction Industries. Carbide Tooling Is Actually A Ceramic/Metal Composite, Where Metallic Cobalt Acts As A Binding (Matrix) Material To Hold The Wc articles In Place. This Type Of Industrial Use Accounts For About 60% Of Current Tungsten Consumption.
The Jwellery Industry Makes Rings Of Sintered Tungsten Carbide, Tungsten Carbide/Metal Composites, And Also Metallic Tungsten. Wc/Metal Composite Rings Use Nickel As The Metal Matrix In Place Of Cobalt Because It Takes A Higher Luster When Polished. Sometimes SUPPLIERSs Or Retailers Refer To Tungsten Carbide As A Metal, But It Is A Ceramic Because Of Tungsten Carbide's Hardness, Rings Made Of This Material Are Extremely Abrasion Resistant, And Will Hold A Burnished Finish Longer Than Rings Made Of Metallic Tungsten. Tungsten Carbide Rings Are Brittle, However, And May Crack Under A Sharp Blow.
THe Hardness And Density Of Tungsten Are Applied In Obtaining Heavy Metal Alloys. A Good Example Is High Speed Steel, Which Can Contain As Much As 18% Tungsten. Tungsten's High Melting Point Makes Tungsten A Good Material For Applications Like Rocket Nozzles, For Example In The Ugm-27 Polaris Submarine-Launched Ballistic Missile. Tungsten Alloys Are Used In A Wide Range Of Different Applications, Including The Aerospace And Automotive Industries And Radiation Shielding.Superalloys Containing Tungsten, Such As Hastalloy And Stellite, Are Used In Turbine Blades And Wear-Resistant Parts And Coatings.

High purity tungsten rods can be used as heat conductor, additive, crankshaft and cylinder barrel of automobile, parts of heat-resistant steel and electrode. High purity tungsten rods are mainly used in guns, rockets, satellites, airplanes and ships.
The purity (99.999%) tungsten bars are mainly used as materials for high standard bearing steels, automobiles, high-speed railways, high precision equipment, and high-tech weapons. The purity (99.99%) tungsten bars are mainly used in alloy tool steel, high quality clean steel, and high performance special steel, etc. The purity 99.95% tungsten products are mainly used to cast raw materials for ingredients and forging special steel and drawn steel wires.

Pure tungsten heavy metal plate is widely used in the construction of furnace tooling and parts and as a feedstock for the fabrication of parts for the electronics and semiconductor industries. Surface can be supplied in a shiny or matte; dependent upon thickness and width parameters
Tungsten has the highest melting point (3410°C or 6170°F) of all metals. The extremely high melting point of pure tungsten makes all the common manufacturing techniques used for metals such as iron impractical. Specialized methods make possible the processing of pure tungsten into rod, sheet, and wire for a wide variety of high temperature applications including incandescent lamp wire, TIG welding electrodes, high temperature heat shielding, etc
Since tungsten heavy metal has highest melting point among all the pure metals in the world,pure tungsten heavy metal plate is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace, sputtering target applied in plasma coating film, and high temperature resistance boat.
Tungsten is mainly used in the production of hard materials based on tungsten carbide, one of the hardest carbides, with a melting point of 2770 °c. wc is an efficient electrical conductor, but w2c is less so. wc is used to make wear-resistant abrasives, and "carbide" cutting tools such as knives, drills, circular, mining and turning tools used by the metalworking, woodworking, mining, petroleum and construction industries. carbide tooling is actually a ceramic/metal composite, where metallic cobalt acts as a binding (matrix) material to hold the wc particles in place. this type of industrial use accounts for about 60% of current tungsten consumption.
The jewellery industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. wc/metal composite rings use nickel as the metal matrix in place of cobalt because it takes a higher luster when polished. sometimes SUPPLIERSs or retailers refer to tungsten carbide as a metal, but it is a ceramic because of tungsten carbide's hardness, rings made of this material are extremely abrasion resistant, and will hold a burnished finish longer than rings made of metallic tungsten. tungsten carbide rings are brittle, however, and may crack under a sharp blow.
The hardness and density of tungsten are applied in obtaining heavy metal alloys. a good example is high speed steel, which can contain as much as 18% tungsten. tungsten's high melting point makes tungsten a good material for applications like rocket nozzles, for example in the ugm-27 polaris submarine-launched ballistic missile. tungsten alloys are used in a wide range of different applications, including the aerospace and automotive industries and radiation shielding.superalloys containing tungsten, such as hastalloy and stellite, are used in turbine blades and wear-resistant parts and coatings.
