FEPA Wear-Resistant Powder White Fused Alumina 2000# Export Grade Alumina
White fused alumina is produced from high-purity, low-sodium aluminum oxide powder that is melted at high temperatures in an electric arc furnace to form alumina. Electromelted alumina exhibits excellent toughness and high wear resistance, maintaining high compressive and bending strength even at elevated temperatures. As a result, it is commonly used in industrial applications as a wear-resistant raw material added to coatings, ceramics, resins, and composite materials to enhance their toughness and wear resistance.
FEPA White aluminum oxide 2000# is made from aluminum oxide powder with high purity and low sodium content, which is melted at high temperature in an electric arc furnace to produce alumina. Electromelted alumina has good toughness and high wear resistance, and even at high temperatures, it has high compressive and bending strength. Therefore, in industry, it is often added as wear-resistant raw materials to coatings, ceramics, resins, and composite materials to increase their toughness and wear resistance.
Main Performance Characteristics of White Fused Alumina:
1.The main crystal phase of white fused alumina is α-alumina, offering high wear resistance and excellent toughness.
2.The white fused alumina grit produced by our company is obtained by crushing and screening first-grade white fused alumina from fixed furnaces, exhibiting better toughness than that from tilting furnaces.
3.Wide range of particle sizes available, from 8# to 10000#.
4.Strong chemical stability, high resistance to acids and alkalis, and insoluble in water.
5.Low oil absorption rate.
6.Excellent thermal stability, with wear resistance unaffected at high temperatures.
7.Produced using a special ball milling process, resulting in low metal residue, high whiteness, and no impact on the color of coatings and other products.
8.White fused alumina has a high refractory temperature, resistance to acid and alkali corrosion, and excellent thermal performance.
The main performance characteristics of white corundum:
1. The main crystal phase of white corundum is α Aluminum oxide has high wear resistance and good toughness.
2. The white corundum particle size sand produced by our company is obtained by crushing and screening the first level white corundum in a fixed furnace, and its toughness is better than that of pouring furnace white corundum.
3. It has a wide range of particle sizes and can be selected from 8 # to 10000 #.
4. Strong chemical stability, strong resistance to acid and alkali, insoluble in water.
5. Low oil absorption rate.
6. Strong thermal stability, and the wear resistance at high temperatures is not affected.
7. Produced through a special ball milling process, the metal residue is small, the whiteness is high, and it will not affect the color of coatings and other products.
8. White fused corundum has a high refractory temperature, resistance to acid and alkali corrosion, and good thermal performance.
