Silicon Carbide Abrasives Silicon Carbide Blasting Media
Silicon Carbide Abrasive FEATURES. Silicon carbide media is even harder than aluminum oxide. In fact, synthetic silicon carbide is the hardest abrasive blasting media in use today. Silicon carbide offers the benefit of an extremely fast cutting speed, which, when combined with its hardness, allows for much shorter blasting times.

Silicon Carbide Abrasives Abrasive Products
Abrasives remove material from a workpiece. Sanding discs, sanding belts, sandpaper, deburring tools, and other industrial abrasive products eliminate rough edges, nicks, and notches from metal workpieces or shave off layers of wood. Grinding and cut-off wheels cut, grind, sand, or finish metal, glass, wood, brick, or concrete surfaces.

Sandblasting vs. Abrasive Blasting: What's the Difference?
Mar 26, 2020· Abrasive blasting goes by many different names, including abrasive jet machining, pencil blasting, abrasive micro-blasting, micro-abrasive blasting and more. No matter the name, the process includes using gas to propel abrasive materials at high velocity to wear away the surfaces of particularly brittle, heat-sensitive, hard or thin materials.
