Silicon Carbide Grit Blasting Media
Silicon Carbide Grit is the hardest abrasive media. This blasting media has very fast cutting action and can be recycled and re-used many times. The hardness of Silicon Carbide Grit allows for shorter blast times relative to other blasting media.
Silicon Carbide Grit Blasting Media
Silicon carbide blast media is the top performer in abrasive materials—unyielding, sharp, and built to cut through the toughest surfaces. With a naturally blocky, angular grain shape, this material continuously fractures into razor-like edges, delivering an ultra-fast, aggressive blast. If you’re looking to finish strong and finish fast, silicon carbide sandblasting would be the right choice.
Outranking nearly everything but diamond and boron carbide on the MOHS hardness scale (clocking in around 9.5), silicon carbide sandblasting media works where softer abrasives fail. Its abrasive power slashes blast times and amplifies productivity. Think of it as precision with extreme cutting efficiency in a controlled form.
Used repeatedly in tumblers, silicon carbide blast media breaks down gradually, forming a perfect mix of particle sizes. This evolving grit blend makes cleaning and polishing incredibly effective, especially when paired with rock tumbling or dark wood sanding. Add a little fresh grit, and the cycle starts anew—sharp edges ready to go again.

Frequently Asked Questions (FAQs)
Q1. What is silicon carbide blast media?
Silicon carbide blast media is a synthetic crystalline abrasive known for its exceptional hardness (Mohs 9.5), sharp angular shape, and fast-cutting capabilities. It’s ideal for aggressive surface prep and precision cutting.
Q2. What are the main applications of silicon carbide blasting media?
- Rapid paint, rust, and scale removal
- Etching and texturing glass, stone, and ceramics
- Cleaning hard metals like titanium or stainless steel
- Lapping and polishing
- Tool and die prep
- Precision surface prep in aerospace and electronics industries
Q3. How does silicon carbide compare to aluminum oxide?
- Harder (Mohs 9.5 vs 9.0)
- Sharper, more friable – cuts faster, but breaks down quicker
- Ideal for fine, detailed work and hard surfaces
- May not last as long in reusable applications
Q4. Is silicon carbide reusable?
It is partially reusable but has a lower recycling life than aluminum oxide due to its friability—it fractures easily during use.
Q5. Is silicon carbide suitable for use on all materials?
It’s not recommended for soft or sensitive surfaces, as it is highly aggressive. Best suited for hardened metals, ceramics, and glass.
