Brown Fused Alumina

DOMILL is a manufacturer specializing in brown fused alumina, which is known as brown fused aluminum oxide or brown aluminum oxide. Brown Fused Alumina is fused in an electric arc furnace and produces a high strength, tough, and extremely durable grain. DOMILL fuses them by two different ways, which are Molten Block Method and Dumping Method. Different Method makes different characteristics.

brown fused alumina main picture

Molten Block Method makes the brown fused alumina with less crystalline aggregate, large crystal size, less glassiness, good toughness, high wear resistance, but its brittleness is slightly lower than that of Dumping Method. The brown fused alumina made by Molten Block Method needs to be graded before it is processed into grains, and DOMILL selects them in strict accordance with the requirements. The made grains have the advantages of high purity, stable chemical properties, are suitable for coated abrasives manufacturing.
Dumping Method makes the brown fused alumina with the advantages of more crystal aggregate, small crystal block size, less glassiness, good brittleness, but its toughness is slightly lower than that of Molten Block Method.
The made grains have the advantages of high purity, stable chemical properties, uniform particles, low magnetism, good self-sharpness, are suitable for bonded abrasives manufacturing and refractories.
Brown fused alumina also can be widely used as a raw material in ceramics,blasting media, polishing and other applications. The DOMILL brown fused alumina grains and powders can be made by standard of ISO, FEPA, ANSI,JIS,GOST, also by customer’s specific requirement.
