Wearable Sandblasting Boron Carbide (B4C) Venturi Nozzles with Longer Service Life Competitive Prices

Material: Boron Carbide (B4C).
Jacket: Aluminum / Polyurethane Protector.

The hardness of boron carbide is only secondary to diamond and CBN. The density of the boron carbide products produced by us is close to its academic density 2.52g/cm3The advantages are: longer service life, high hardness, high wear-resistance ability, anti-corrosion,  lower cost per use, reducing down time. It's the ideal material for sandblasting nozzle and mechanical seal.

The gas dynamics of venturi nozzle is better than straight-hole nozzle, the vortex is improved or ceased to exist, greatly reduced the pressure loss in the same pressure conditions. Abrasive exports increased to more than double the speed, efficiency than the straight-hole nozzle to increase 15% -40%, 20% lower abrasive consumption.

Boron carbide can be used to manufacture gun nozzles in the arms industry, which is extremely hard and wear-resistant, no reaction with acid-base, high/low temperature resistance, high pressure resistance, crystal system: hexagonal, density: 2.52g/cm3, Mohs hardness: 9.36, microhardness 5400-6300kg/mm2, bending strength ≥400Mpa, melting point: 2450ºC. Because it has the characteristics of wear resistance and high hardness, Boron Carbide Sandblasting Nozzle will gradually replace the known carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials sandblasting nozzle in the future.

High Quality Boron Carbide Powder (B4C) with Mohs Hardness 9.36

Boron Carbide Powder (B4C) a black crystal powder, is one of the hardest Man-Made materials, its hardness with Mohs hardness 9.36 and microscopic hardness 5400-6300kg/mm2 is only near upon diamond, its density is 2.52g/cm3 and melting point is 2450ºC, The boron carbide possesses properties of endurance hi/low temperature, no reaction with either acids or alkalis, high grinding efficiency, no magnetism. It is a good replacement of diamond. Boron carbide also possesses the special properties of light quality, neutron absorbing, semi-conductivity, etc., so it is used for armed forces and nuclear industry.
Boron carbide is widely applied as follows: boriding refractory, ion transfusion, film layer as well as grinding, polishing, drilling hard metal alloys, jewels, etc. Meanwhile, it is main material for the wear-resisting parts, precise meter-age element, precise spray nozzle, sealed washer, smelting boron steel, boron alloy, etc.
Boron carbide has showed many better properties of physics and chemistry in the hi-science/technology field.
