Description:W Tungsten nanopowders is with high melting point, high thermal conductivity, good mechanical properties, with low sputtering yield, excellent mechanical strength, low tritium retention, and high erosion resistance. The nano scale Tungsten powders are with uniform particles, high activity and large specific surface area. Nano tungsten powder is widely used in aerospace alloys, electronic packaging alloys, electrode materials, microelectronic films, sintering aids, protective coatings, gas sensor electrodes, etc. To process the high performance ultra-fine nano crystalline alloys by nano tungsten powder and high specific gravity alloys which is widely use in many high-tech fields. The cemented carbide produced by nano tungsten powder has extremely high hardness and is a leading product of tungsten materials.Tungsten nanopowders can be sintered to Tungsten compacts with high relative density in relatively low temperature and pressure.Storage Condition:Tungsten (W) nanopowders should be stored in sealed, avoid light, dry place. Room temperature storage is ok.SEM & XRD :
