White fused alumina

White fused alumina is a high-quality blasting and grinding abrasive for demanding high-tech applications. It is especially suitable wherever an iron-free material with very high purity, a high degree of whiteness and extreme hardness is required.

Typical fields of use include medical technology, aerospace, optical industry, electrical engineering, refractory products, bonded abrasives, loose abrasives, coated abrasives, wear protection and wet or dry blasting applications.
