Dongguan Humen Meijun Sandblasting Equipment Boron Carbide Nozzle Features:
Compared to products from other companies, we guarantee:
1) High-temperature sintered boron carbide products with high hardness, toughness, wear resistance, and long service life.
2) Neat and glossy appearance.
3) High roundness for outer diameter and inner hole.
4) Ensured to be sintered from pure boron carbide micro-powder, no substitute materials are used, making it pure boron carbide material.
Hot-pressed High-Temperature Furnace Boron Carbide Nozzle Performance Features: Same properties as boron carbide:
The cross-section features a helical radioactive pattern, with the basic nozzle shape being cylindrical and conical, making it challenging to produce irregular and stepped designs.
Very hard and wear-resistant
2) Non-reactive to acids and alkalis
3) Withstanding high and low temperatures, and high pressure
4) Density ≥ 2.5 g/cm³
5) Micro-hardness ≥ 3500 kgf/mm²
6) Bend strength ≥ 400 Mpa
7) Melting point: 2450°C.
Due to the above features of high wear resistance and hardness, boron carbide nozzle has gradually replaced known hard alloys such as tungsten steel, silicon carbide, silicon nitride, aluminum oxide, and zirconia in industries requiring wear resistance.
Estimated nozzle lifespan: 800 hours (reference)
Boron carbide nozzles have a lifespan 5-10 times longer than tungsten carbide nozzles!

Boron carbide is a dark black hexagonal crystal. Due to its unique characteristics and properties, it is widely used in mechanical, metallurgical, chemical, aerospace, and other fields. It can be used as an abrasive for processing gems, ceramics, bearings, and as refractory material in various metallurgical applications. Dongguan Humen Meijun Sand Blasting Equipment's "Magin" brand boron carbide nozzle is made from high-purity, hard materials, using ultra-fine, high-purity boron carbide powder as raw material. It is produced through hot-pressing and high-temperature sintering technology. The product takes into account the high lifespan requirements of many manufacturers, continuously improving and optimizing. After being applied by numerous large-scale glass deep-processing, electronic manufacturing, and metal die-casting enterprises, it has truly achieved a balance between cost and performance, earning high praise from manufacturers. The product has been steadily supplied to Hong Kong, Taiwan, and Southeast Asia, and has gained a certain amount of sales in Europe and America, winning the trust of many customers!
Customer base includes sandblasting machinery manufacturers, shipyards, ship repair facilities, marine engineering equipment factories, metal processing plants, glass deep processing facilities, solar industry, photovoltaic and photoelectric industries, wind power generation sector, automotive industry, IT manufacturing, oil industry, mold etching factories, die casting factories, hub factories, chip factories, metal factories, coating factories, oxidation factories, electroplating factories, and other enterprises with high demand for sandblasting machine accessories.
