Mono-crystalline Aluminium Oxide 2A-Yellow use industrial alumina as the main raw material, adding composite additives, and melting at high temperatures. Good sharpness equal to white corundum and high toughness to brown corundum or chrome corundum. It can be used as raw material when makeing resin abrasive disks and coated milling tools, and also can be used for cutting and grinding special steel, especially for dry-grinding and making workpieces wich are easy-out-of-shape and easy getting burnt. All kinds of binders can be adopted when utilizing Single Crystal Aluminium Oxide 2A to make grinding tools.
Mono-crystalline Aluminium Oxide 2A is light yellow color.
