Electrically fused in arc furnace with high grade processed alumina
as raw material. It has higher hardness and slight lower toughness
ring with brown fused alumina. It is also characterized by its high
purity, ability of self-sharpening, better cutting, less heat emit,
higher efficiency, acid and alkali resistance, good thermal
stability. As the abrasive materi
als, it is suitable for grinding high-speed, high carbon steel, as
ins,it widely used for bonded and coated abrasives , polishing,
precision casting and so on .
The main advantages of white corundum
(1) does not affect the color of the workpiece;
(2) can be used in the process of iron powder is strictly
prohibited to blasting;
(3) fine powder level is very suitable for wet sandblasting and
(4) high processing speed and high quality;
(5) the amount of iron oxide contained in the extremely low
forbidden iron residue sandblasting operations;
(6) After the pickling step to remove impurities, the alumina
content is higher.
