Semi-friable fused alumina is low titanium brown fused alumina. Since its hardness and toughness is between white fused alumina and brown fused alumina, we call semi-friable fused alumina. It is characterized by high temperature resistance, corrosion and erosion resistance, low apparent porosity and stable thermal stability. Its grain is characterized by strong self-sharpening, sharp grinding edges and not easy to burn workpiece. We have strict control about company & quality;Our service is full-around and first-class. Typical Chemical Analysis in Weight% (Grit 24) Grit F24 Al2O3 TiO2 SiO2 Fe2O3 Chemical composition 97.62 1.54 0.45 0.14 So we're your wise choice. Don't hesitate to contact us.
