Customized Sand Blasting Boron Carbide (B4C) Venturi Nozzles
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/cm3. We supply high quality customized boron carbide B4C nozzles with longer service life.(One of our customers told us that our B4C nozzles are probably the most wear-resistant nozzles they've ever used, over 468 hours for aluminum oxide abrasives! Not 180 or 230 hours he got from other Chinese suppliers.)
The 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.
Note: Special requirement on specifications can be satisfied through discussion.
Kumthai's boron carbide nozzles can be customized. Please tell us the specifications and send us the drawings, we will make a quotation according to your drawings and send the prices to you for your reference.
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.
