Silicon Carbide

Silicon carbide is the hardest blasting media available. High-quality silicon carbide media is manufactured to a blocky grain shape that splinters. The resulting silicon carbide abrasives have sharp edges for blasting. Silicon carbide has a very fast cutting speed and can be recycled and reused many more times than either sand or aluminum oxide. .

Silicon carbide grit is the ideal media for use on glass and stone in both suction or siphon and direct pressure blast cabinets. The ability to be recycled multiple times results in cost-effective

Since silicon carbide grit is harder than aluminum oxide, it can be used efficiently for glass and stone etching. Silicon carbide grit blast media has no free silica, does not generate static electricity and is manufactured to contain minimal magnetic content.

Silicon carbide grit is brittle and sharp and can be used on wheels for grinding metal and nonmetallic materials of low tensile strength such as gray cast iron, brass, aluminum, stone materials, leather and rubber
