Pink Fused Alumina F80-F180铬刚玉磨料


       Pink Fused Alumina F80-F180铬刚玉磨料是一种刚玉质磨料,颜色呈粉红色或者玫瑰红色,它是磨具生产中常用的高韧性磨料。铬刚玉的冶炼加入了氧化铬物质,高温下与氧化铝反应生成一种比白刚玉韧性更好、比重更高的刚玉磨料。铬刚玉是为研磨而生的磨料,具有高强度、高韧性、高堆积密度、高亲水性,兼顾普通刚玉磨料的硬度和自锐性。用它制成的磨具产品,磨削力和使用寿命都有很大提升。用铬刚玉作为研磨砂,可以提高研磨效率,适用于多种金属、合金制品的磨削。

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.
