Fused White Alumina

Product description White corundum is made of high quality aluminum oxide powder as raw material, refined and crystallized by electric melting. It has high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance and stable thermal performance. Its hardness is slightly higher than that of brown corundum.It is suitable for grinding fine grain abrasive such as high carbon steel, high speed steel and stainless steel. chemical component Physical characteristics size AL2O3 8# 10# 12# 14# 16# 20# 22# 24# 30# 36# 40# 46# 54# 60# 70# 80# 90# 100# 120# 150# 180# 220# 240# â?¥99.5% 0-1mm 1-3mm 3-5mm 5-8mm â?¥99.5% 100#-0 200#-0 320#-0 â?¥99% FEPA:F230 F240 F280 F320 F360 F400 F500 F600 F800 F1000 F1200 F1500 F2000 JIS:#240 #280 #320 #360 #400# #500 #600 #700 #800 #1000 #1200 #1500 #2000 #2500 #3000 #4000 #6000 #8000 â?¥99.2%

Product Description Fused White Alumina(WA) Abrasive grains White Alumina ,a kind of high-grade refractories, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

We are the biggest supplier of white fused alumina in china, we are also the standard setter of the white fused alumina in china.We have been in the industry since 1987. White corundum: fused alumina is widely used as a raw material in refractories, ceramics shapes, grinding wheels, sandpaper, blasting media, metal preparation, laminates, coatings, lapping, polishing, grinding and hundreds of other applications.Zhengzhou yufa, white fused alumina grains and powders are available in standard grit and powder sizes and they can also be made to individual specifications.

White Fused Alumina (white corundum) WFA Abrasive blasting media is made of 99% aluminum oxide powder as raw material, which is refined and crystallized by electric melting (thus white corundum is also called fused alumina and white fused alumina). The white corundum sand produced by our factory has high purity, low impurities, low sodium content, uniform particles and high whiteness.

The white corundum sand produced by our factory has high purity, low impurities, low sodium content, uniform particles and high whiteness. Product Feature 1. The Al2O3 purity is high(99%min). So the hardness & grinding ability is high with good grinding efficiency. 2. High wear-resistance. Even in high-temperature circumstances, the strength is still excellent. 3. The white fused aluminum oxide powder is suspension treated by water. So it is of flowability and easy to scatter. 4. Low oil absorption especially for water-based paint. 5. Neutral property with PH value around 7-8. 6. High whiteness. It doesn't affect the color of paints or coatings adding Al2O3 powder. 7. Resistant to most corrosive alkali and acid. It doesn't dissolve in water. 8. Resistant to high temperature up to 1900 C. 9. Good particle size consistency without big size grains. So it prevents scratch on the grinding substrate.

White Fused Aluminium Oxide (WFA)� is widely used for Abrasive Tools, Sandblasting, Polishing, Surface Preparation. Our WFA is a hard, dense and iron-free material with highest purity, hence is an ideal abrasive material. It also has above 95% Al2O3 content, high degree of whiteness, extreme hardness and a wide range of precise grit sizes.
