Pink Fused Alumina Abrasives
Products Description
Pink fused alumina abrasives are a kind of high-performance alumina-based abrasive material that features excellent hardness, toughness, and self-sharpening ability. It is made from high-quality bauxite, iron-free kaolin, and other raw materials through high-temperature smelting in an electric arc furnace.


These abrasives are widely used in various grinding and cutting applications such as surface preparation, rust, and corrosion removal, precision grinding, and polishing of different types of materials including steel, alloy, and non-metallic materials. It is especially useful in applications where high-speed grinding and a fine surface finish are required.
Pink fused alumina abrasives have several characteristics that make them superior to other abrasive materials. They have a high level of strength and wear resistance, excellent thermal stability, and outstanding electrical insulation properties. Furthermore, they have a low coefficient of thermal expansion, making them ideal for precision grinding applications.

In terms of their composition, pink fused alumina abrasives mainly consist of aluminum oxide (Al2O3) with small amounts of titanium oxide (TiO2) and silicon dioxide (SiO2). Additionally, it has a unique crystalline structure that enables it to perform at high levels of efficiency while minimizing wear and deformation.
