Brown Fused Alumina Abrasive Grit For Surface
Brown Fused Alumina is widely used as an abrasive material in various applications such as grinding, cutting, polishing, and sandblasting. It is also used as a refractory material in high-temperature applications, such as in the production of steel, cement, ceramics, and glass. Additionally, Brown Fused Alumina is used in surface preparation, surface finishing, and in the manufacturing of abrasives, grinding wheels, sandpaper, and other abrasive tools.
説明
Description
Brown Fused Alumina Abrasive Grit is a high-quality abrasive material commonly used for surface preparation in various industries. It is made from calcined bauxite and iron filings fused in an electric arc furnace. The resulting material is hard, durable, and chemically inert, making it ideal for a range of abrasive applications.
The abrasive grit is available in different sizes and shapes, including angular, blocky, and sharp-edged grains. It is commonly used for blasting, grinding, and polishing metal surfaces, as well as for cleaning and preparing concrete, stone, and other surfaces for further treatment.
Brown Fused Alumina Abrasive Grit is highly resistant to wear and tear, making it ideal for use in high-stress applications. It also has excellent thermal and chemical stability, making it suitable for use in harsh environments. Its low iron content makes it suitable for use on stainless steel, while its high hardness makes it ideal for removing tough coatings and corrosion from metal surfaces.
