Silicon carbide abrasives are hard and sharp materials used in sandpaper, with razor-sharp grains for efficient metal, stone, and medium-density fiberboard sanding applications with minimal pressure application. Unfortunately, silicon carbide wears down more quickly than its aluminum oxide counterparts due to brittleness and narrow grain size differences between grains. High hardness Silicon carbide grinding wheels boast superior hardness to aluminum oxide abrasives, withstanding extreme stress without becoming worn or frayed. Furthermore, silicon carbide materials feature higher chemical resistance compared with many ceramic materials and thus protecting from chemical corrosion. Due to these properties, silicon carbide grinding wheels are widely used across applications. Corundum and silicon carbide abrasives are among the …
