Product Introduction

Pink Fused Alumina

 

Product description

 

Chromium corundum is made of aluminum oxide powder as the main raw material, suitable for chromium oxide and so on, through high temperature smelting. It is pink, similar to white corundum in hardness and higher in toughness than white corundum. The abrasives manufactured by the utility model have good durability and high grinding finish. It is suitable for precision grinding of measuring tools, instrument parts, threaded workpieces and sample plates.

Production process

 

The smelting process of chrome corundum is the same as that of white corundum, but a certain amount of chromium oxide is added in the smelting process, which is light purple or rose color. Cr3 + is introduced into chrome corundum to improve the toughness of abrasives. Its toughness is higher than that of white corundum, and its hardness is similar to that of white corundum. When it is used to process materials with higher toughness, its processing efficiency is higher than that of white corundum, and the surface finish of workpiece is also better. Chrome corundum is suitable for processing workpieces with high toughness, such as quenched steel, alloy steel, precision measuring tool and instrument parts, etc.

Product use

 

1. Chrome corundum is characterized by pink color, high hardness, high toughness, high purity, excellent self sharpening, strong grinding force, small heat output, high efficiency, acid and alkali corrosion resistance, high temperature resistance and good thermal stability.

 

2. Ideal sand blasting, suitable for sand blasting of hardware, glass, zinc alloy, aluminum alloy, stainless steel, high carbon steel, high speed steel, etc. In particular, the effect of thin wall workpiece is obvious, the workpiece does not change color, and the machining finish is high.

 

3. It can improve the finish of silicon wafer, optical lens, precision instrument, polished glass shell, glassware, ceramic stone, leather, plastic and metal parts.

 

4. The grinding tool made of it is sharp in grinding, low in heating rate, high in grinding ratio, and less in use; the sintered grinding tool made of it has the characteristics of dark blue after firing, no network cracks and no rust spots.

 

5. The abrasives made of chrome corundum have good durability and high grinding finish. It is suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and pattern grinding.

 

6. Chrome corundum is suitable for manufacturing ceramics, resin high consolidation abrasive tools, grinding, polishing, etc.
