Product Introduction
First Class Brown Corundum is a high-quality abrasive product made from premium bauxite and smokeless coal. It is produced in an electric arc furnace at temperatures over 2200℃, through multiple processes such as purification, impurity removal, crystallization, selection, crushing, magnetic separation, and screening. It features high hardness, great strength, impact resistance, high temperature resistance, oxidation resistance, corrosion resistance, and low creep. This makes it suitable for manufacturing ceramics, resin bonded abrasives, as well as grinding, polishing, sandblasting, and precision casting.
Product Advantages
Excellent Wear Resistance
First Class Brown Corundum is renowned for its exceptional wear resistance, attributed to its Mohs hardness of 9.0, second only to diamond and a few natural minerals. Its high hardness allows it to withstand greater pressure and friction during cutting, grinding, and polishing processes, with minimal self-wear. Compared to conventional abrasives, the lifespan of First Class Brown Corundum can be extended by over 30%, significantly reducing replacement frequency and costs.
Superb Corrosion Resistance
The product boasts a stable chemical composition and exhibits outstanding resistance to corrosive substances such as acids and bases. In industries like chemicals and ceramics, even in highly corrosive environments, First Class Brown Corundum maintains its performance, ensuring processing quality and efficiency. Within a pH range of 3-11, its mass loss rate is below 0.5%, far superior to the average of similar products.
High Thermal Stability
First Class Brown Corundum can withstand temperatures up to 1600°C without losing its physical and chemical properties, making it exceptional in applications like high-temperature cutting, welding assistance, and refractory material manufacturing. Under high-temperature conditions, it effectively resists thermal shock, preventing cracks and fragmentation, and maintaining the flatness and precision of the cut surface.
High-Precision Processing
Utilizing advanced production techniques, First Class Brown Corundum features a uniform particle distribution and precise sizing, meeting the demands of precision processing. Its fine particle structure results in extremely high surface finish after processing, reaching below Ra 0.2 micrometers, suitable for high-requirement fields such as optical lenses and precision mechanical parts. This characteristic not only enhances the aesthetic appeal of products but also boosts their functionality, like reducing friction resistance and improving sealing properties.
