Abstract
An abrasive article is provided that may include a body. The body may include a bond component and abrasive particles within the bond component. The bond component may include a Fe—Co—Cu—Ni—Sn based bond material and a performance enhancing material. The performance enhancing material may include hex-boron nitride. The content of the performance enhancing material may be at least about 6 vol. % and not greater than about 14 vol. % for a total volume of the bond component.
