Product Overview:
Brown Fused Alumina is a hard, sharp abrasive that’s ideal for grinding metals with high tensile strength. Its thermal properties make it an excellent refractory material. This substance is also used in blasting and surface hardening applications. After the crude is cooled, it undergoes further crushing and cleaning of magnetic impurities in high-intensity separators.
The abrasive tools made by brown fused alumina are suitable for grinding carbon steel, normal alloy steel, malleable cast iron and hard bronze, etc. Brown fused alumina can also be used for making fine quality refractory etc.
Advantages:
Brown Fused Alumina has the is featured by high packing density, high purity, compact texture, good self sharpening, good toughness and low magnetic content.

The high hardness of fused alumina enables it to maintain sharp cutting edges, resist wear, and provide consistent abrasive performance, making it suitable for challenging grinding and cutting applications.
Scratches appear in the polishing process because there are large grains in the abrasive product, resulting in a poor product appearance and poor cleanliness.
Fused alumina offers excellent thermal shock resistance, high refractoriness, and chemical stability, making it an ideal material for refractory linings in furnaces, kilns, and other high-temperature environments.
Quality control measures, such as rigorous testing, particle size analysis, chemical composition verification, and adherence to industry standards, help ensure the consistent quality and performance of fused alumina products.
