WHITE CORUND
WHITE CORUND
White corundum is a high purity aluminium oxide that is suitable for machining stainless steel and aluminium. This non-iron, reusable blasting agent combines angularity, roughness and hardness. Thanks to this, this mineral has a very strong abrasive effect on the blasted surface.
