Pink fused aluminum oxide is a type of corundum abrasive with a pink or ruby pink color. It is a commonly used high toughness abrasive in the production of grinding tools. The smelting of chromium corundum involves the addition of chromium oxide material, which reacts with alumina at high temperatures to produce Pink fused alumina with better toughness and higher specific gravity than white corundum. Pink Fused aluminum oxide is an abrasive material designed for grinding, which has high strength, toughness, bulk density, hydrophilicity, and combines the hardness and self sharpening properties of ordinary corundum abrasives. The grinding tool products made with it have greatly improved grinding force and service life. Using chromium corundum as grinding sand can improve grinding efficiency and is suitable for grinding various metal and alloy products.
