Which is harder, white corundum or brown corundum? The hardness of corundum is actually determined by the content of alumina. The higher the content, the higher the hardness. The alumina content of white corundum is ≥99.5%, and the content of brown corundum is ≥94.5%. Therefore, the hardness of white corundum is greater than that of
Comparison table of the differences between white corundum micro powder and available micro powder White Corundum Micro Powder Comparison Table Physical Properties White Corundum Micropowder Crystal form trigonal crystal system Density 3.90 g/cm3 Pore Nupp porosity 2000-2200Kg/mm2, Mohs porosity 9.0 Melting point 2250℃ High operating temperature 1900℃ Specific heat (Cal/g.C)0.26 (20-90C) Thermal pressure 900C (Cal/cm3.sec.C)
White corundum micropowder is an abrasive whose main component is manufacturing. It is used in glass manufacturing, glass process improvement, 1. Glass manufacturing In the glass manufacturing process, white corundum micro-powder abrasives are used on the surface of flat glass, bottle glass and other products. By using white corundum micropowder for grinding, scratches, visible defects
Application of white corundum in precision casting As a widely used material, white corundum also has irreplaceable advantages in the precision casting industry. White corundum itself has high strength and relatively low expansion coefficient. It will not expand and crack when the temperature is high. Precision castings have relatively high requirements for flatness. White corundum
White corundum manufacturer base The base of white corundum manufacturers is mainly in China. China is also the largest producer and exporter of corundum materials in the world. However, we are not yet a powerhouse in corundum material production technology and processing technology. Compared with the world’s industrial pattern, in terms of production technology and
What should we pay attention to during the process of white corundum sandblasting and rust removal? 1. After the sandblasting operation is completed, the surface of the workpiece needs to be cleaned to avoid re-contamination. 2. White corundum can be recycled and recycled after use, and can be repeatedly sandblasted and ground. White corundum abrasives
