The main raw material of boron carbide blasting gun is one of the hardest man-made materials. It has the characteristics of light weight, semiconductor properties, neutron absorption, high grinding efficiency, and does not react with strong acids and alkalis. , 36, micro hardness of 5400-6300 kg per square meter, density of 2.52 kg per square meter, melting point of 2450 degrees Celsius, boron carbide is hexagonal dark black.
Features of boron carbide products: it has the same performance as boron carbide, is extremely hard and wear-resistant, does not react with acids and bases, and is resistant to high, low, and high pressure, with a density ≥ 2.46 g / cm3. Micro hardness ≥3500kgf / mm2, flexural strength ≥400Mpa, melting point 2450 ℃. Boron carbide sandblasting nozzles can replace the known cemented carbide and silicon carbide, silicon nitride, alumina, zirconia and other materials. The life of the high-speed secondary air inlet sand blasting nozzle produced by our company can reach 1,000 hours, and the inner diameter of the nozzle wears 1-2 mm.
