White fused alumina

Low iron content

White Fused Alumina is mainly used as a recyclable abrasive in blast cabinets and blast rooms, where high purity of the abrasive is required. Because of its low iron content, white alumina is often used in blasting operations where iron contamination on the non-ferrous metal substrate is not allowed.

Corundum white is one of the purest fused alumina and it is very hard and sharp with a fast cleaning rate. It leaves a sharp anchor profile prior to coating and is suitable for removal of scale, rust and old coating layers.
