The formation of uniformly high quality abrasive compacts, especially cubic boron nitride compacts, is achieved by employing a substrate material (comprising a carbide such as tungsten carbide and a ferrous metal such as cobalt) having a titanium content of not greater than 100 ppm as shown by analysis. Preferably, the maximum tantalum content is also not greater than 100 ppm.
