Web10 de mai. de 2007 · It has high chemical purity (more than 99 percent Al 2 O 3) that gives it an aggressive, cool, fast-cutting action. White-fused aluminum oxide holds its form well. It is used to grind heat-sensitive alloys. These applications make use of its friability and the fact that it cuts without generating high heat. WebHigh friability indicates low fracture resistance. Aluminum oxide (A1 2 0 3 ) has lower friability than silicon carbide (SiC); thus, it has less tendency to fragment and self …
