White Fused Alumina – EK

White Fused Alumina belongs to the group of electro-corundum. It is produced by controlled melting of alumina in an electric arc furnace. White fused alumina is iron-free, ultra pure and extremely hard.

Applications:

Reusable abrasive
Grinding, lapping and polishing media
Ceramic grinding wheels and grinding media
Wear-resistant and refractory products

Blasting systems:

Pressure blast systems
Injection blast cabinets
