Silicon carbide sanding is a common method used in industrial surface finishing, especially where a fine cut and high precision are required. Silicon carbide (SiC) is a synthetic abrasive that is extremely hard and sharp, making it highly effective for sanding hard materials such as glass, ceramics, stone, and non-ferrous metals.
In this article, we’ll explore what silicon carbide sanding is, its key properties, and how it compares to other common abrasives used in the market.
Silicon carbide is a compound of silicon and carbon. When fused at high temperatures in an electric furnace, it forms sharp, hard crystals ideal for abrasives. Compared to traditional abrasives like aluminum oxide, SiC breaks down faster but cuts more aggressively, which is excellent for certain surface treatments.
During sanding, the sharp edges of silicon carbide grains remove material rapidly. Unlike aluminum oxide, which wears down slowly, SiC fractures easily, continuously exposing new sharp edges. This makes it ideal for tasks where speed and surface quality are important.
SiC sanding is widely used in:
| Feature | Silicon Carbide | Aluminum Oxide |
|---|---|---|
| Cutting speed | Fast | Moderate |
| Durability | Moderate | High |
| Surface finish | Very smooth | Rougher |
| Recommended use | Hard surfaces, glass, ceramics | Wood, steel, general purpose |

Yes, for hard surfaces like glass or stone, SiC is sharper and cuts faster. For wood and steel, aluminum oxide may be more durable.
Absolutely. It performs very well in wet applications, reducing dust and producing a finer finish.
We supply a full range from F12 to F1500 and finer micro-powders on request. See our grit size chart for details.
