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

•  High Hardness: Surface hardness of forged steel ball is to 60-68 HRC 
•  High Impact Toughness: The impact toughness is more than 15 J/cm2
•  Low Broken Rate: The actual broken rate is not higher than 1%;
•  High Wear-resistance: The wear rate of cast ball is 50-700 g/ton.
