1. Performance of Pink Fused Alumina
Hardness and Wear Resistance
Pink fused alumina boasts an extremely high hardness, with values ranging from 2500 to 2600HV, which is approximately 15% to 20% higher than that of regular diamond grinding wheels. This superior hardness makes it an excellent choice for processing materials with high hardness requirements such as high-speed steel, alloy steel, and cemented carbide. Its wear resistance is also exceptional, allowing it to maintain a high surface quality even under high-speed grinding conditions.
High-Temperature Stability
The material exhibits excellent stability at high temperatures, without undergoing phase changes or softening. This makes it suitable for manufacturing materials that are resistant to wear, oxidation, and corrosion at high temperatures, such as high-temperature furnaces, heat treatment equipment, and high-temperature pipelines.
Chemical Stability
Pink fused alumina also possesses good chemical stability, resisting chemical reactions with other materials. It demonstrates strong corrosion resistance in a variety of strong acids, strong bases, and organic solvents, making it ideal for the production of chemical equipment and fuel cells that require high chemical stability.
Toughness and Applications
Furthermore, pink fused alumina has high toughness and purity, with excellent self-sharpening properties, strong grinding force, low heat generation, and high efficiency. These characteristics make it an ideal abrasive for sandblasting and polishing applications, particularly for materials such as hardware, glass, zinc alloy, aluminum alloy, stainless steel, high carbon steel, and high-speed steel. It is especially effective in sandblasting thin-walled workpieces, resulting in non-discolored parts with a high degree of processing smoothness. Chrome corundum can also be made into grinding tools, which are sharp, have a low heat generation rate, high grinding ratio, and minimal adhesion during use. Sintered grinding tools made from chrome corundum are characterized by their deep blue color after sintering, absence of mesh cracks, and rust-free appearance.
