AC3497 Fused Brown Alumina

Brown Aluminium Oxide Description

Brown Fused Alumina is an exceptionally durable and resilient material known for its toughness. Its brown colour results from a slightly higher level of impurities compared to white aluminium oxide. With a Mohs hardness of 9, brown fused alumina exhibits extraordinary strength and wear resistance, allowing it to withstand harsh chemical attacks from acids and bases, even at extreme temperatures. This material finds widespread application in processes such as blasting and grinding.

Brown Fused Alumina Applications

1. Abrasives and Grinding Applications: Used as a high-performance abrasive in grinding wheels, sandpaper, and blasting. Due to its high hardness and toughness, brown fused alumina is suitable for heavy grinding and surface preparation tasks in metalworking, automotive, and construction industries.

2. Refractory Materials: Utilised in refractory bricks, castings, and moulds for high-temperature applications such as furnace linings, combustion additives, and crucibles. Brown fused alumina improves thermal stability, thermal shock resistance, and erosion resistance in harsh industrial environments.

3. Sandblasting and Surface Preparation: Used as a blasting medium for cleaning, deburring, and preparing metal surfaces before coating or painting. It effectively removes rust, scale, and old coatings, ensuring a uniform surface texture.

4. Precision Casting and Investment Casting: Employed in precision casting processes for the production of complex metal parts with fine details and smooth surfaces. Brown fused alumina is used as mould material or ceramic shell in investment casting to achieve high dimensional accuracy and surface quality.

5. Ceramic and Glass Manufacturing: Utilised as a raw material for producing ceramic bodies, refractory ceramics, and special glass products. It enhances the strength, durability, and thermal properties of ceramic and glass components.

6. Lapping and Polishing: Used in lapping and polishing to achieve precise flat surfaces and optical components. Abrasives made from brown fused alumina are used in the manufacture of lenses, mirrors, and semiconductor materials.

7. Water Filtration: Serves as a filter medium in water filtration systems to remove impurities, turbidity, and contaminants from drinking water and industrial wastewater. Due to its high purity and low abrasion rate, it is suitable for filtration applications.

8. Cosmetics and Personal Care: Incorporated into cosmetic products, toothpaste, and skin care products as a mild abrasive to remove dead skin cells and improve skin texture.

9. Aerospace and Automotive Industries: Utilised in the production of aerospace and automotive components such as brake pads, clutch discs, and engine parts. The high strength, thermal conductivity, and wear resistance of brown fused alumina contribute to improved performance and durability.

10. Chemical Processing: Used in the chemical industry for abrasive applications and as a catalyst support material in chemical reactions where high hardness and stability are required.
