The wear resistance of tungsten carbide sandblasting nozzles depends mainly on their material hardness and structural design. Tungsten carbide has an extremely high hardness of about 9.5-9.7, second only to diamond. This gives tungsten carbide blasting nozzles excellent abrasion resistance to resist abrasion and the impact of abrasive particles during high-speed blasting.
The structural design of tungsten carbide sandblasting nozzle also plays an important role in its wear resistance. Usually, tungsten carbide blasting nozzles use internal coating or surface treatment to enhance their surface hardness and wear resistance.
