Pink fused alumina is a high-quality mineral abrasive known for its extreme hardness and particularly sharp edges. The addition of chromium oxide gives it its characteristic pink color. Pink fused alumina is produced using special high-temperature processes and is ideal for applications that require the highest precision and gentle surface treatment.
Our customers use both pink fused alumina and white fused alumina as a blasting medium and abrasive. However, the addition of chromium oxide makes pink fused alumina tougher and more durable. We will be happy to help you.
