Property: Made from aluminum oxide powder by high-temperature smelting in an electric arc furnace.
Characteristics: The Al203 content is generally higher than 98%, with higher hardness than brown corundum and lower toughness than brown corundum, indicating good cutting performance.
Usage: The grinding tool made of it is suitable for grinding quenched alloy steel, high-speed steel, etc. Fine grained grinding powder can also be used for precision casting.
