Stable In Acidic And Alkaline Environments Fused Aluminium Oxide High Mohs Hardness 9 Ideal For Cutting And Sandblasting Processes

Product Description:

Fused Aluminum Oxide, also known as Fused Aluminium Oxide, is a high-quality abrasive material widely used in various industrial applications, especially in precision casting products. With the chemical formula Al2O3, this compound is a crystalline form of aluminum oxide that exhibits exceptional hardness, thermal stability, and chemical inertness, making it an ideal choice for demanding manufacturing processes. The product typically appears in colors ranging from white to gray, reflecting its purity and the specific conditions under which it is synthesized.

One of the most notable variants of this material is Brown Corundum, which shares many similar properties but is distinguished by its coloration and particular uses. Fused Aluminum Oxides, including Brown Corundum, are manufactured through the fusion of high-purity alumina in an electric arc furnace. This process results in a dense, hard, and angular abrasive with excellent performance characteristics, especially in applications requiring high wear resistance and durability.

The particle size of Fused Aluminum Oxide used for precision casting products generally ranges from 2 to 3 millimeters. This size distribution is carefully controlled to ensure optimal packing density and surface finish when used as a refractory or abrasive material. The granules’ angular shape and consistent size contribute to their superior mechanical strength, making them highly effective in sandblasting, grinding, polishing, and other abrasive processes involved in precision casting.

Another critical property of Fused Aluminum Oxide is its refractive index, which is approximately 1.76. This refractive index indicates the material's ability to bend light, a property that is important in optical applications but also provides insight into the material’s density and purity. The relatively high refractive index of fused aluminum oxide ensures that it maintains structural integrity under intense light and heat exposure, which is often encountered during precision casting processes.

Due to its exceptional hardness—second only to diamond and silicon carbide—Fused Aluminum Oxide is highly valued in industries that require materials capable of withstanding extreme mechanical stress. Precision casting products benefit immensely from the use of this abrasive because it allows manufacturers to achieve fine surface finishes and tight dimensional tolerances. The durability of fused aluminum oxides also means less frequent replacement and lower operational costs, enhancing overall efficiency in production environments.

In addition to its mechanical properties, Fused Aluminium Oxide is chemically stable and resistant to most acids and alkalis, which further extends its applicability in harsh industrial environments. This chemical resistance ensures that the abrasive does not degrade or contaminate the casting materials, preserving the quality and integrity of the final products. As a result, it is widely used in foundries and metalworking industries where precision and reliability are paramount.

Moreover, the thermal stability of Fused Aluminum Oxide is a significant advantage in high-temperature applications such as precision casting. The material can withstand temperatures well above 2000°C without melting or deforming, which prevents contamination and maintains the structural properties of casting molds and cores. This makes fused aluminum oxides an indispensable component in the production of high-quality metal parts and components.

In summary, Fused Aluminum Oxide (Al2O3) with its white to gray color, particle size of 2-3mm, and refractive index of 1.76, represents a superior abrasive material tailored for precision casting products. Whether in the form of Brown Corundum or other fused aluminum oxides, this material offers unmatched hardness, chemical stability, and thermal resistance. These attributes collectively ensure that fused aluminum oxide remains a preferred choice for industries aiming for excellence in precision manufacturing and abrasive applications.
