Silicon Carbide Abrasive


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. This results in a lower per-hour cost than most other abrasive media types. As with aluminum oxide blast media, silicon carbide is recyclable and can be reused many times.

What Is Silicon Carbide Abrasive?

Silicon carbide is a ceramic material containing hard, abrasive grains that break down under pressure. This breaking down process makes SiC items cut faster and sharper and generate finer scratch patterns on a wide range of surfaces. Silicon carbide is considered one of the hardest materials — besides diamonds — because another substance cannot scratch it.

When it comes to blasting media, silicon carbide is widely popular due to its low cost and long-lasting properties. Abrasive blasting is the process of using specialized machinery to project media at high speeds across a hard surface. Often, abrasive blasting is used to power away rust, prepare a surface for painting or remove old finishes on a product’s surface.

In addition to prepping surfaces for high-performance coatings, silicon carbide abrasive blasting media applications include:

  • High-performance etching and frosting
  • Micro-blasting on metal and glass
  • Etching and carving of glass and hard metals
  • Metal, stone and glass engraving

What Are the Benefits?

Silicon carbide is used as an abrasive due to its hardness. What sets the ceramic material apart from other abrasives is its high-temperature strength, high thermal conductivity and low thermal expansion. First, manufacturers mold silicon carbide grit into an angular grain shape. Silicon carbide media then begins the process of breaking down constantly to yield incredibly sharp edges.

Benefits of silicon carbide abrasive follow:

  • Silica-free design
  • Shorter blast times compared to other media
  • Minimal contaminants and magnetic content
  • Rapid cutting speed
  • Composition lighter than metallic with a denser blast stream
  • Low cost
  • Light to very heavy etching on a variety of surfaces
  • Availability in a wide range of grit sizes and mesh
  • Biodegradable and reusable material

Does Silicone Carbide Abrasive Work Better in One Industry vs. Another?

Silicon carbide abrasives can be used in automobiles, electric systems, power electronic devices and LEDs, quantum physics, graphene production, steel production, carborundum printmaking, jewelry, thin filament pyrometry, astronomy and more. They work best in industries and manufacturing sectors that require reliable metal cleaning, finishing and preparation. Industries that benefit from silicon carbide abrasive are:

  • Antique stove refinishing
  • Lighting for blasting applications
  • Truck bed preparation
  • Outdoor lighting pole blast finishing and etching
  • Jewelry polishing
  • Industrial spray booths
  • Hydraulic fluid reservoir blasting
  • Deburring and polishing
  • Air makeup units for paint booths
