Semi-friable Fused Alumina is created through the fusion of a unique blend of bauxite and Bayer-alumina, along with additive minerals, in an electric arc furnace. The high purity of alumina contributes to a crystal with increased hardness compared to regular brown fused alumina, while the presence of additive minerals enhances toughness, surpassing that of white and pink fused alumina. As a result, ASF exhibits exceptional cutting performance and provides a durable tool life. Chemical Composition (Grit 46): - Particle Size Distribution: Available in F8–F1200, adhering to the PSD according to FEPA standard 42 and GB/T 2481. Customization based on JIS, ANSI, or specific customer requirements is also offered. - Bulk Density (g/cm3): Custom shapes, including blocky and sharp shapes, can be accommodated upon special customer request.

To enhance the performance of grains even further, standard brown fused alumina undergoes a ceramic coating on the surface following a heat treatment at 1350 degrees Celsius through open annealing. This process is denoted as "HTCC."

To withstand high-stress working conditions, semi-friable fused alumina undergoes a heat treatment at 1350 degrees Celsius through open annealing. This process results in a color transformation from light brown to light blue. The treatment is specifically designed to rejuvenate the majority of crystal imperfections and alter the crystal lattice by introducing foreign oxides. Consequently, the grains experience improvements in both cutting quality and tool life. This treatment is denoted as "HT."

To enhance the bonding characteristics of grains, semi-friable fused alumina can undergo a surface modification through ceramic coating. This coating facilitates the creation of a ligament between the grains and resin. Simultaneously, the heat treatment applied during the process serves to modify the crystal structure, leading to increased toughness in the grains. This treatment is identified as "CC."
