Density 3.95 Gcm3 Fused Alumina High Hardness 9 Mohs Abrasive Powder for Precision Surface Finishing and Wear Resistance

Product Description:

Fused Aluminum Oxide, also commonly referred to as Fused Alumina or Fused Aluminum Oxides, is a high-quality, advanced material known for its exceptional hardness and durability. This industrial-grade abrasive is widely used in various applications including grinding, polishing, sandblasting, and refractory products. It is manufactured through the fusion of high-purity alumina in an electric arc furnace, resulting in a crystalline powder with superior physical and chemical properties.

One of the most notable characteristics of Fused Aluminum Oxide is its remarkable hardness, rated at 9 on the Mohs scale. This places it just below diamond, making it an ideal abrasive for cutting, grinding, and polishing hard materials such as metals, stones, ceramics, and glass. The hardness of Fused Alumina ensures excellent wear resistance and long service life, significantly enhancing the efficiency and cost-effectiveness of industrial processes.

The density of Fused Aluminum Oxide is approximately 3.95 grams per cubic centimeter (G/cm³). This relatively high density contributes to its substantial mass and strength, providing excellent stability during use. The dense nature of Fused Alumina also allows it to withstand extreme mechanical stresses and thermal shocks, which is crucial in high-temperature environments and demanding applications.

Fused Aluminum Oxide is typically available in particle sizes ranging from 2 to 3 millimeters. This specific particle size range offers a balanced combination of surface area and mass, making it suitable for various abrasive applications. The granules provide a consistent texture that ensures uniform abrasion and efficient material removal. The controlled particle size distribution helps optimize the performance of Fused Alumina in processes such as sandblasting, grinding wheels, and refractory linings.

In terms of appearance, Fused Alumina presents itself as a white to gray crystalline powder. This color variation depends on the purity and specific manufacturing processes used during fusion. The crystalline nature of the powder contributes to its sharp edges and angular particles, which are essential for effective abrasive action. The uniformity in appearance also reflects the high-quality standards maintained during the production of Fused Aluminum Oxide.

Chemically, Fused Aluminum Oxide is composed of aluminum oxide with the formula Al2O3. This chemical composition underpins its outstanding physical and chemical stability. Al2O3 is known for its excellent resistance to chemical corrosion and high melting point, making Fused Alumina suitable for use in harsh environments where chemical inertness and thermal stability are required. This makes it a preferred choice in refractory applications, where it serves as a key component in furnace linings, kiln furniture, and other high-temperature industrial equipment.

In summary, Fused Aluminum Oxide is a versatile and robust material characterized by a hardness of 9 Mohs, a density of 3.95 G/cm³, and a particle size of 2-3mm. Its white to gray crystalline powder appearance and chemical formula of Al2O3 highlight its high purity and quality. Known interchangeably as Fused Aluminium Oxide, Fused Aluminum Oxides, or Fused Alumina, this product is indispensable across numerous industries due to its superior abrasion resistance, thermal stability, and chemical inertness. Whether used in abrasive blasting, grinding, polishing, or refractory applications, Fused Aluminum Oxide consistently delivers excellent performance and reliability.
