The difference between white corundum and single crystal corundum？

White corundum is made of high-quality aluminum oxide powder as raw material, which is refined and crystallized by electric melting. It has a slightly higher hardness than brown corundum, slightly lower toughness, high purity, good self-sharpening, strong grinding ability, low heat generation, high efficiency, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability. It is used to make abrasives suitable for grinding high-carbon steel, high-speed steel, etc. It can also be used as grinding, polishing materials, precision casting, spraying materials, chemical catalyst carriers, special ceramics, advanced refractory materials, etc.

Features of white corundum abrasives
1. Imported aluminum oxide powder is used to ensure high product quality;
2. The testing means are complete, and a national accredited laboratory has been built to ensure the stability of quality;
Sandblasting white corundum is widely used in special ceramics such as precision casting, steel refractory, chemical refractory, decorative porcelain, and daily life porcelain, as well as high-tech industries such as military industry and electronics.
Single crystal corundum is made of alumina powder as the main raw material, smelted at 2250℃ in an electric arc furnace, and then crushed and hydrolyzed and processed. The products of various particle sizes are produced by natural crystallization, not mechanical crushing. Because its particles are composed of a single crystal, it has good multi-faceted cutting edges, high hardness and toughness, strong grinding ability, and low grinding heat.
Application range
It is a very good heat-resistant high-grade grinding material, used to make advanced cutting and grinding tools, suitable for grinding high-hardness and high-toughness materials such as high-vanadium high-speed steel, austenitic stainless steel, heat-resistant alloy steel, titanium alloy, etc., especially suitable for dry grinding and grinding of workpieces that are easy to deform and burn.
Production process
Single crystal corundum (also known as SA) is made of alumina powder as the main raw material, smelted at 2250℃ in an electric arc furnace, crushed and hydrolyzed, and selected.
