White Fused Alumina0-1-3-5

1.high quality products and the most competitive prices 2.high-grade refactory materials

white aluminium oxide is a high-quality aluminium oxide powder as raw materials, smelting fusde together. It  has the color white ,high hardness, low toughness, high purity, excellent self-sharpening, grinding power, heat, high efficiency,acid corrosion, high temperature, thermal stability and good features.It is not only advanced abrasives materials,and or advanced grinding, polishing steel and stainless steel. It is also widely used in precision casting, steel fire-resistant, chemical resistant.
