Dongguan Humen Meijun Abrasive Blasting Equipment Boron Carbide Nozzle Features:
Compared to products from other companies, we guarantee:
1) High-temperature sintered boron carbide products, featuring high hardness, toughness, wear resistance, and long service life.
2) Clean and glossy appearance.
3) High roundness of outer diameter and inner hole.
4) Ensured to be sintered from pure boron carbide micro-powder, no other materials are used as substitutes, it is pure boron carbide material.
The hot pressing high-temperature furnace sintered boron carbide nozzle features the same properties as boron carbide:
The cross-section features a spiral radioactive pattern, with the basic nozzle shape being cylindrical and conical, making it difficult to produce irregular and stepped designs.
Extremely hard and wear-resistant
2) Non-reactive to acids and alkalis
3) Withstanding high and low temperatures, as well as high pressure
4) Density ≥ 2.46 g/cm³
5) Micro-hardness ≥ 3500 kgf/mm²
6) Bending strength ≥ 400 MPa
7) Melting point: 2450°C.

Due to the high wear resistance and hardness characteristics of boron carbide nozzles, these nozzles have gradually replaced known hard alloys in industries that require high wear resistance.
Welding nozzles made of tungsten carbide, silicon carbide, silicon nitride, alumina, zirconia, and other materials.
Estimated nozzle lifespan: 800 hours (reference)
Boron carbide nozzles have a service life 5-10 times longer than tungsten carbide nozzles!

Properties of Boron Carbide materials:
Boron carbide is one of the hardest artificial materials, characterized by its light weight, semiconductor properties, neutron absorption, high grinding efficiency, and resistance to strong acids and bases. It has a Mohs hardness of 9.36, a microhardness of 5400-6300 kg/mm², a density of 2.52 kg/m², and a melting point of 2450°C. Being dark black in the hexagonal system, its unique features and properties make boron carbide widely used in mechanical, metallurgical, chemical, aerospace, and other fields. It can be used as an abrasive for processing gems, ceramics, and bearings, and as refractory material in various metallurgical applications.
Dongguan Humen Meijun Sandblasting Equipment's "Magin" brand Boron Carbide Sandblasting Nozzles are made from high-purity, hard materials, using ultra-fine, high-purity boron carbide micro-powder as raw material. They are produced through hot pressing and high-temperature sintering technology. The products have been continuously improved to meet the high lifespan requirements of many manufacturers. After being applied by numerous large-scale glass deep-processing, electronic manufacturing, and metal die-casting enterprises, they have truly achieved a balance between cost and performance, earning high praise from manufacturers. The products have been steadily supplied to Hong Kong, Taiwan, and Southeast Asia, and have gained a certain amount of sales in Europe and America, winning the trust of many customers!
Our client base includes sandblasting machinery manufacturers, shipyards, ship repair facilities, marine engineering equipment factories, metal processing plants, glass deep processing, solar industry, photovoltaic and photoelectric industry, wind power industry, automotive industry, IT manufacturing, oil industry, mold etching factories, die casting factories, hub factories, chip factories, metal factories, coating factories, oxidation factories, and electroplating factories, all of which have a high demand for sandblasting machine accessories.
