Product description
Brown aluminum oxide grit for Sand Blasting F20-F180
Haixu Brown fused alumina is made of bauxite, anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000 degrees. Abrasives tools made by Haixu brown fused alumina are suitable for metal with high tensile(like: steel, malleable iron, bronze etc). Suitable for product high consolidation abrasive, and suitable for grinding, polishing, blasting, precision casting etc. Haixu brown fused alumina is also used for refractory material. Brown fused alumina with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.
Product advantage
1.High hardness around Mohs 9.0.
2.High toughness which is a little higher than white fused alumina.
3. Good grinding ability.
4.A quality level with high Al2O3 purity and low TiO2 impurity.
5. Low Fe2O3 content with magnetic removal treatment.
6.Good grain shape with high bulk density.
7. Narrows particle size range.
