Pink Fused Alumina

Pink fused alumina is made of alumina powder as the main raw material, add some chromium oxide, etc., high temperature smelting.It is pink, the hardness is similar to white fused alumina, and the toughness is higher than white fused alumina.Abrasives made of it have good durability and high finishing finish.It is suitable for precision grinding of measuring tools, instrument parts, threaded workpieces and sample grinding.

The smelting process of Pink fused alumina is the same as that of white fused alumina, except that a certain amount of chromium oxide is added during the smelting process, which is light purple or rose.Since the introduction of Cr3+ in pink fused alumina improves the toughness of the abrasive, its toughness is higher than that of white fused alumina, and its hardness is similar to that of white fused alumina. When used for processing tougher materials, its processing efficiency is higher than that of white fused alumina, and the surface finish of the workpiece is also Better, chromium corundum is suitable for processing high toughness hardened steel, alloy steel, precision measuring tools and instrument parts and other workpieces with high finish requirements.

According to the chromium oxide content Pink fused alumina is divided into low chromium, medium chromium and high chromium.

Pink fused alumina has the characteristics of pink color, high hardness, high toughness, high purity, excellent self-sharpening, strong grinding power, low heat generation, high efficiency, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability. It is also called Pink aluminum oxide, Pink aluminium oxide, Pink corundum, Chromium corundum, Red aluminum oxide etc.

Applications:

1.Pink fused alumina is suitable for manufacturing ceramics, resin high-consolidation abrasive tools, grinding, polishing, etc.

2.Ideal sandblasting material, suitable for sandblasting of hardware, glass, zinc alloy, aluminum alloy, stainless steel, high carbon steel, high speed steel, etc.In particular, the effect of spraying thin-walled workpieces is obvious, the workpiece does not change color, and the processing finish is high.

3.It can improve the smoothness of silicon wafers, optical lenses, precision instruments, polished glass bulbs, glassware, ceramic stones, leather, plastics, and metal parts.

4.The abrasive tools made of it have sharp grinding, low heat generation rate, high grinding ratio, and little adhesion during use; the made sintered abrasive tools have a dark blue color after firing, no net cracks, and no rust spots. Features. And good durability, high grinding finish. It is suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and model grinding.
