Abstract
An abrasive article including a body having a bond material extending throughout the body and including at least 8 wt % aluminum oxide (Al2O3) for a total weight of the bond material, and also including unagglomerated abrasive particles including silicon carbide (SiC) contained within the bond material and present in an amount of greater than 30 vol % for a total volume of the body.
Claims20
An abrasive article comprising:
- a body including:
- a bond material extending throughout the body, wherein the bond material comprises at least 8 wt % aluminum oxide (Al2O3) for a total weight of the bond material and not greater than 56 wt % silicon dioxide (SiO2) for the total weight of the bod material;
- and
- unagglomerated abrasive particles comprising silicon carbide (SiC) contained within the bond material and present in an amount of greater than 30 vol % for a total volume of the body.
