production method
1) The product can be obtained by the secondary oxidation and re-reduction technology of tungsten powder.

2) Use the granulation and sintering method to produce spherical powder.

3) It can be prepared by rotating electrode DC arc plasma method.

4) Preparation of large particle powder from tungsten hexafluoride by vapor deposition method.

5) The ordinary tungsten powder is spheroidized and air-cooled with an inductively coupled plasma torch to obtain the product.

Spherical tungsten powder is the main raw material for the production of tungsten alloy, tungsten material and cemented carbide. W powder can be mixed with other metal powders to make tungsten alloy; W powder can be processed into tungsten materials such as tungsten rods, tungsten wires, tungsten bars; W powder can be made into tungsten carbide powder after carbon treatment, and tungsten carbide powder can be made into Cemented carbide tools such as milling cutters, drills and dies.

Matters needing attention: Due to the high melting point and hardness of spherical tungsten powder, it is prone to defects such as cracks, deformation, and sandwiching during processing, which in turn affects the properties of the alloy. With the advancement of science and technology, 3D printing technology has gradually replaced the traditional powder metallurgy method, and is currently an ideal tungsten powder processing technology.
