The carbide nozzle is mainly applied to the nozzle for mechanical equipment operation, such as cold spraying, thermal spraying, vacuum coating, sandblasting, spray, liquid injection, laser processing, etc. Carbide nozzle has good physical stability, high hardness, high wear resistant and corrosion resistant,which can meet the requirements of jet spray very well, so it is widely applied in aerospace, marine engineering and advanced manufacturing. , rail transit and other fields.
Sintered tungsten carbide
products including various sand blasting nozzle, high-pressure water spray nozzle, high-pressure water cutting nozzle, bars, sheets, sealing rings, punching die blocks, glass cutters, etc.
Advantages on Tungsten carbide sand blasting nozzles :
1. very high hardness.
2. stable working effort during blasting.
3. long sizes are accetable.
4. very good prices with quite fast delivery.
5. special sizes with drawing are acceptable.

Boron carbide sand blasting nozzles
Boron carbide have a service life 4-7times of sintered tungsten carbide nozzles, but their shock resistance is not as that of sintered carbide nozzles, so are suitable to serve under wear, stable atmospheric pressure and medium shock.
Specification:
Grind resistant, do not active with acid, low & high temperature resistance,
The density> =2.46g/cm3;
Hardness> =3500kgf/sqm, bending resistance: ≥ 400Mpa
Melting point: 2450degree
And now boron carbide nozzle is instead of hardness alloy, Tungsten carbide nozzle, silicon carbide sandblasting nozzle.
The working life of boron carbide nozzle is 500-1000H
The size can be customized as per drawing
Size/Feature/Application:
Grade: YG8, YG10, YG11, YG12, etc.
Size:According to customer requirements. Customized also welcome.
