White Fused Alumina

White fused alumina(WFA) is made of industrial aluminum oxide powder, which is smelted at a high temperature above 2000 ° C in electric arc and then cooled. After grinding and shaping, the iron is removed by magnetic separation and screened into various particle sizes.

Brown Fused Alumina

Brown fused alumina is made of bauxite, coke (anthracite) as the main raw materials, and is smelted at high temperature in arc furnace. It is a grinding tool made of it, suitable for grinding metals with high tensile strength, such as all kinds of common steel, malleable iron, hard bronze, etc..

Bubble Alumina

MAGMA Bubble Alumina is a rigid, low-density, insulating refractory aggregate. While Bubble Alumina exhibits a bulk density twice that of a premium -grade alumina fiber insulator, Bubble Alumina’s structure consists primarily of closed air-filled thin-walled cells which combine to give it exceptional hot strength and low thermal conductivity.
