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 powder is used for casting, and its good dispersion can meet the casting requirements. Using white corundum micro powder to participate in the production process, the stable thermochemical properties can ensure that there will be no layering. At the same time, because the white corundum powder has high temperature resistance and good sand-sticking resistance, it can achieve a good fixed-line effect.
