What Is The Magic That Makes Pink Raw Materials So Popular in The Industrial Field?

Chromium corundum is primarily produced using high-purity alumina (Al₂O₃) as a base, with the addition of 1.5%–3.0% chromium oxide (Cr₂O₃). It is then melted in an electric arc furnace at temperatures above 2000°C and cooled to crystallize, forming a high-grade abrasive. The presence of pink fused aluminum oxide gives it a denser crystal structure, higher hardness, and stronger wear resistance. Its color ranges from pink to purplish-red, and it is commonly used for high-precision grinding, polishing, and machining of high-temperature workpieces.

Products with strong adaptability are always popular, regardless of time or place. Our high-quality chromium fused aluminum oxide ensures high surface precision and a mirror finish while performing precision grinding on stainless steel and mold steel. In polishing ceramic, glass, and alloy surfaces, its high heat resistance prevents thermal stress cracking, resulting in excellent processing performance. Furthermore, it improves cutting performance and lifespan in grinding wheel and grinding head manufacturing, while also enabling low-impurity, pollution-free processing, meeting the requirements of precision grinding.

High hardness and high-temperature resistance ensure that chromium fused aluminum oxide maintains its sharpness even under heavy loads and high temperatures. Excellent wear resistance is also essential for effectively extending the life of cutting tools. To ensure the consistency of our chrome corundum products, we have successfully achieved uniform particles, excellent formability, and a particle size deviation of ≤±1.5%.

Cutting efficiency is the key determinant of processing speed and production costs, while wear life directly influences the frequency of tool and grinding wheel replacement. Furthermore, controlled thermal stability prevents grain softening and reduced cutting performance at high temperatures. These key properties make our chrome corundum more resistant to thermal degradation at high temperatures than white fused alumina sand, maintaining a stable and sharp cutting edge during metal cutting.
