White Aluminum Oxide(WA/White Fused Alumina) Lumps
Different size of lumps is ordered, such as 0-1mm, 0-2mm, 1-3mm, 0-0.5mm, 5-7-8mm, 5-10mm, 10-20mm etc. It will often need 7-15 days for quantity 15 to 400 tons per order. Packing is also could be ordered for different displays regarding your requirements.
It has white color, high hardness (Mohs hardness: 9.0), high melting point(2200 degree centigrade), high purity (AL2O3:99.5%Min), high temperature resistance characteristic, very stable chemical characteristic.
The powder and grit are widely used for abrasive media, sandblasting, polishing and grinding on metals surface treatment, such as steel, stainless steel, high carbon steel, high speed steel. It is also used for refractory materials, abrasion resistance additive, hardware decoration. And it is commonly used for making ceramics at industrial grade, food grade, for electronics. For beauty additive, it is also commonly in recent years.
The abrasive tools made of it are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel.
Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory, for sandblasting, and abrasive etc.
