SiSiC sand blasting nozzle is the main wear-resistant component in the blasting machine.
It is one of the key components of mechanical equipment, such as surface strengthening, surface cleaning, surface coating, surface modification, and jet cutting.
The extreme hardness makes these materials excellent choices for nozzles in high-wear applications. The life span is 5-10 times that of the ordinary material.
Features:
High hardness and wear resistance
High thermal stability
Outstanding thermal shock resistance
Excellent corrosion resistance to acids, alkalis, and high-temperature gases
High strength and dimensional stability
Long service life in harsh environments
Applications：
Used as sand nozzle, water sand cutting nozzle, and coal spray nozzle for steel plant, thermal power plant, and other industries.
