Superfine spherical tungsten powder has the advantages of fine grain, good fluidity and good mechanical properties. It is widely used in manufacturing precision tools, precision molds and wear-resistant parts.
Characteristic
Superfine spherical tungsten powder has a fine grain size (< 0.5mm), good fluidity, high hardness, abrasion resistance, red hardness and high toughness.
Application
Superfine spherical tungsten powder is the raw material of high quality X-ray tube tungsten target and thickness of tungsten foil. It is also the raw material for the manufacture of ultra-fine grain hard alloy.
It is widely used in the manufacture of metal cutting tools, printed circuit board micro drills, dot matrix printer needles and other precision tools, precision molds, wear-resistant parts, etc. In the field of thermal spraying, due to the good fluidity of spherical tungsten powder, the coating made of it has better wear resistance.
Preparation
Using plasma technology, which can realize the spheroidizing, elaboration and densification of tungsten powder, the preparation of ultra-fine spherical tungsten powder, tungsten powder after the plasma treatment at the same time from irregular into spherical shape, average particle size is greatly reduced, and tap density increased significantly.
