Boron Carbide Industrial Sandblasting Nozzles 4.8mm-12.7mm Sand Blasting Gun Nozzle

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

The hardness of boron carbide is second only to diamond and CBN.The density of our boron carbide products is close to its academic density of 2.52g/cm3.Advantages: longer service life, high hardness, high abrasion resistance, corrosion resistance, lower cost per use, and reduced downtime. It is the ideal material for sandblasting nozzles and mechanical seals.
The gas dynamics of venturi nozzles are superior to those of straight orifice nozzles, vortices are improved or no longer exist, greatly reducing pressure loss under the same pressure conditions. Abrasive exit velocity is increased to more than twice, efficiency is increased by 15%-40% compared to straight orifice nozzles, and abrasive consumption is reduced by 20%.
Boron carbide can be used in the manufacture of gun nozzles for the arms industry, which is extremely hard and wear-resistant, does not react with acids and alkalis, resistant to high and low temperatures, resistant to high pressure, crystal system: hexagonal, density: 2.52g/cm3, Mohs hardness: 9.36, microhardness 5400-6300kg/mm2, bending strength ≥ 400Mpa, melting point: 2450ºC. Due to the wear-resistant, hardness, high, Boron Carbide Blasting Nozzle will gradually replace the known carbide/tungsten steel and silicon carbide, silicon nitride, alumina, zirconia and other materials of sand blasting nozzle in the future.

Applications:

Boron carbide is used in a wide range of applications including: boronized refractories, ionic infusions, membrane layers, and grinding, polishing, lapping, and drilling carbide, sapphire, and gemstones. At the same time, it is the main material for wear-resistant parts, precision ageing components, sandblasting nozzles, precision nozzles, sealing gaskets, smelting boron steel, boron alloys and so on.

Boron carbide shows many better physical and chemical properties in high-tech field.

Key Configurations:

Boron carbide powder (B4C) is a black crystalline powder, is one of the hardest man-made materials, its hardness is 9.36 on the Mohs scale, microhardness is 5400-6300kg/mm2, only close to diamond, density is 2.52g/cm3, melting point is 2450ºC, boron carbide has a high/low temperature resistance, does not react with acid or alkali, high grinding efficiency, non-magnetic. It is a good substitute for diamond. Boron carbide also has special properties such as light quality, neutron absorption, semi-conductivity, etc., so it is used in the armed forces and nuclear industry.
