We offer three main blends specific for lapidary tumbling applications:

Because black silicon carbide is harder than aluminum oxide, it is generally used for the abrasive wheel, slurry, refractory and ceramic industries. Silicon Carbide is special in the way it breaks down. As it breaks down into smaller particles, the media will expose new, sharp edges. Therefore, black silicon carbide can be best used over and over, such as in a rock tumbler. Simply keep adding new coarser grit, and as the media breaks down, it will create a "working blend" of particles.

Silicon Carbide has a lower hardness and abrasive capacity than diamond and boron carbide. Yet because of its much lower cost when compared with diamond or B4C, it is widely used for grinding nonferrous materials, finishing tough and hard materials, as well as filling up ceramic parts. It is therefore perfect as a rock tumbling media.

Other common applications include:
