White Al2O3 Abrasive Grain
white aluminum oxide grit is a white abrasive made from industrial alumina powder (Al2O3) with a content of over 98% and a small amount of iron oxide and silicon oxide. It is a white abrasive which is melted at high temperature. Its hardness is slightly higher than that of brown corundum and its toughness is slightly lower. It is made by smelting and cooling above 2000 degrees in arc, grinding and shaping, removing iron by magnetic separation, and sieving into many kinds of granularity. It is compact in texture, high in hardness, and sharp in shape.
High hardness and dense particles. Single-particle roundness is good.
The color is pure white, no impurities, to ensure the wear-resistant layer or wear-resistant paper color and transparency.
Uniform distribution of particle size, single-particle shape consistent, with a small amount of wear-resistant effect.
Chemical stability and acid, alkali no action, high-temperature stability is very good.
Low sodium white fused alumina abrasive grain from HAIXU Abrasive is produced strictly according to FEPA and JIS standard, all products are tested and qualified before shipment.
