      After rolling, the density of tungsten plate is basically close to the theoretical density of tungsten when the deformation is more than 60%. Therefore, it has high strength, uniform internal structure and excellent high temperature creep resistance, which is widely used in the production of the cover plate in the sapphire crystal growth furnace, the tropics in the vacuum furnace, the connector, the sputtering target for plasma coating, and the evaporation of tungsten boats.

      Sintered tungsten rods are mainly used for drawing tungsten wires and forged tungsten rods. Because of the high melting point characteristic of tungsten metal itself, the forging tungsten rod with high purity, high density and excellent resistance to high temperature creep is widely used in the tungsten crucible support in the sapphire growth furnace, the electrode in the high temperature furnace, the heating element, the connector, the supporting rod and so on.



      tungsten rod:


      Product Name: tungsten tube
      Product category: a series of sapphire furnace growth
      Brand: W-1
      Density: 18.0g/cm3
      Specifications: Crucible:: (80-600) mm x L (80-1000) mm dimension tolerance: + 0.5mm.
      Tube:: (25-500) mm x L (100-1000) mm dimension tolerance: + 0.5mm.
      Application: mainly used for sapphire crystal growth furnace, rare earth metal smelting, induction furnace heating body, quartz glass melting, etc., as high temperature container. Especially for the sapphire single crystal growth furnace, the tungsten crucible with high purity, high density, no internal crack, accurate size, smooth inside and outside wall, and so on, has played a key role in the success rate of crystal growth, the quality control of the crystal, the dehydration and the service life of the sapphire crystal. This product is made of FW-1 raw material in tungsten powder.
      With the rise and rapid development of the LED industry, the tungsten crucible and tungsten pipe produced by our company rely on the quality of raw materials, fine quality, skilled operation of technical workers and strict quality inspection standards before the factory. It is well received by customers at home and abroad.


      Tungsten wire:

      Size: 0.05mm Application: mainly used for electronic tube drawing line, special lamps such as tungsten wire for halogen lamp, tungsten heat body in high temperature furnace, tungsten wire for vacuum evaporation of electronic industry, welding electrode, white gold contact of automobile engine and other kinds of electric contact of various kinds of electrical appliances. Uses: 1.. Manufacture electric light source and electric vacuum part 2., use 2. as high temperature heating body and high temperature structural part 3.. Appearance: tungsten wire is coated with graphite milk and has a more uniform black.
