Zirgrit® AZ
Zirgrit® NZ
Zirgrit® AZ – Hard and tough blasting grains
The chemical composition of Zirgrit® AZ has been defined in order to achieve improved performance in comparison to fused alumina :
- Longer durability (x3 to x6)
- More consistency in Surface Finish
- Less particle embedment on the blasted substrate
- No ferrous contamination
Zirgrit AZ shows a much longer durability the standard BFA (x3 to x6 depending on size).

Zirgrit® NZ – Dense and sharp blasting grains
Thanks to their specific chemical composition and microstructure, Zirgrit® NZ will provide
- Higher toughness & wear resistance
- Higher density
- Sharper grains
These characteristics provide improved performance in wet-blasting processes, with better separation, high and consistent removal rate.
