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 you wise choice.don¡¯t hesitate to contact us. contact person: melody yang(sales manager) melodyyangmei(at)hotmail.com tel:86-379-65285886-804 mobile phone:13849906514 fax:86-379-65285889 http://www.ycrs.com.cn
