| White Fused Alumina for Abrasive |
White fused alumina is a highly pure form of aluminium oxide which is suitable for use with stainless steel and aluminium. This iron-free, reusable blasting medium is angular, brittle and hard. It has a powerful abrasive effect on the surface being blasted. White fused alumina belongs to the group of fused alumina.
| Feature |
Due to hardness and durability, abrasive is generally reusable for multiple times
Harder than most blasting Media which can achieve fast cutting action
High-melting point
-
Sharp, angular shape. Macro, micro, and custom grit sizes and blends available
