Specifications

Because black silicon carbide is harder than aluminum oxide, it is generally used for the abrasive wheel, slurry, refractory and 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 for recycling, polishing, lapping, and tumbling.

Other common applications include:

Ceramic, metal lapping, and polishing applications

Slicing of silicon carbide wafers

Rock and stone polishing and engraving

Slicing, lapping, and polishing glass and germanium wafers

Lapping of piston rings and gears

Grinding of nonferrous materials

Finishing tough and hard materials

Bonded abrasive tool applications

Glass etching and glass carving industries

Rock tumbling industries

Wholesale Shipping & Packaging Information:

Default Packaging:  Default packaging is in 50lb bags, or 300 lb fiber drums.

Tote Packaging:  We can also package this in 2,200 lb super sacks. (1 metric ton) 

Discount Pricing:  Please use our form to obtain custom pricing on larger quantities, with freight.  Remember to tell us your ship-to address and the total number of lbs or tons you want a bid on. 

Loading Dock:  Generally, you need to have a commercial address with loading dock to receive orders over 200lbs.  If you do not, we can ship it to a local terminal and you pick it up yourself from the terminal.  We can also ship to a residential address, but this is very costly and not recommended.
