APPLICATION OF MACROCRYSTALLINE TUNGSTEN CARBIDE
Macrocrystalline tungsten carbide is a kind of fully carburized and dense tungsten carbide powder with homogeneous microstructure, outstanding thermal stability and coarse particle size. It is with good wetability to Ni, Mn, Co, Fe and Cu and excellent impact resistance. Its particle size ranges from µm to 40 crushing & screening as well as surface treatment, etc.
APPLICATIONS OF MACROCRYSTALLINE TUNGSTEN CARBIDE POWDER:
Macrocrystalline tungsten carbide powder is widely used for:
Making macrocrystalline tungsten carbide powder and mixed with binding metal such as Co to form into hot spray hardfacing material which are PTA welded and HVOF sprayed onto surfaces of airplane engine paper roller chemical devices photocopier and so on.
Macrocrystalline tungsten carbide powder which are able to provide excellent wear resistance against exposed sliding friction surface, such as slot or warehouse crashing parts, forklift buckets, crane hopper, screw feeder, ingot tongs and grind device components.
To be used as cemented carbide for solidifying hard rocks drills, continuous coal mining bits, road construction tools and varies kind of moulds and wear parts. |
