Import Bore Size 7.9mm Siliconcarbide Sand Blast Nozzle — Buy in Bulk from Supplier in China

This sandblast nozzle has a bore size of 7.9mm and is constructed from silicon carbide with a boron carbide liner, designed for high-wear resistance in abrasive blasting applications. It features a coarse or fine thread option for secure mounting and is compatible with steel grit, coal slag, dry ice, walnut shells, and crushed glass abrasives. The nozzle is manufactured using sintering and hot pressing techniques to ensure structural integrity under high-pressure conditions.

Silicon carbide is a standard material in industrial nozzles due to its hardness and thermal stability, typically rated at 9.0 on the Mohs scale. The inclusion of boron carbide as a liner enhances durability when used with harder abrasives like steel grit. Typical service life exceeds 200 hours under continuous use with medium-grade abrasives, though actual lifespan varies with pressure, media type, and operating frequency. This nozzle is not coated or plated; its wear resistance comes from the monolithic composite structure.

It is commonly used in construction, mining, and heavy equipment refurbishment for rust removal, surface profiling, and casting edge smoothing. Buyers include industrial maintenance teams, sandblasting contractors, and manufacturers of heavy machinery. The minimum order quantity is one unit, with packaging in cartons of 30 pieces for sizes 6.4mm to 9.5mm. Custom laser marking and bore sizes are available upon request. Lead time and incoterms must be confirmed directly with the supplier.
