Zirgrit® AZ and Zirgrit® NZ are Alumina – Zirconia composite grains manufactured with the Saint-Gobain unique fusion process. Their superior chemistry and microstructure provide higher efficiency and durability, in comparison to traditional blasting materials like fused alumina.

Zirgrit® AZ and Zirgrit® NZ can be used in all blast cleaning applications as a cost-effective solution to traditional blasting grits, thanks to a much longer durability (x3 to x6), a higher consistency in the surface finish with less particle embedment, and a lower quantity of waste material to handle.

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 :

Zirgrit AZ shows a much longer durability the standard BFA (x3 to x6 depending on size).
