When to Choose Silicon Carbide
Silicon carbide is the hardest commonly available blasting media (9.5 on the Mohs scale, just below diamond). Choose it when you need aggressive material removal: heavy rust, thick paint, heat scale, and hard coatings. It cuts 2-3x faster than aluminum oxide but creates a rougher surface profile. For delicate work or smooth finishes, choose glass bead or baking soda instead.
Surface Profile & Applications
100 grit silicon carbide produces a medium-aggressive surface profile ideal for paint adhesion and coating prep. Common applications include: steel fabrication prep, automotive frame stripping, industrial equipment refurbishment, and marine maintenance.
Frequently Asked Questions
Can I reuse silicon carbide media?
Yes. Silicon carbide is highly durable and can be recycled 3-5 times before the particles break down enough to reduce cutting effectiveness. Use a media classifier screen to separate dust and fines between uses.
Is silicon carbide safe for aluminum parts?
Silicon carbide is very aggressive and can damage soft metals like aluminum, brass, and copper. For aluminum parts, use glass bead or plastic media instead. Silicon carbide is best suited for steel, iron, and hard alloys.

Frequently Asked Questions
How is silicon carbide different from aluminum oxide?
Silicon carbide (SiC) is harder and sharper than aluminum oxide, making it more aggressive for cutting hard materials like stainless steel, titanium, and stone. It costs more but removes material faster.
What grit should I use?
100 grit silicon carbide is a medium-coarse abrasive ideal for aggressive surface preparation and material removal. For finer finishing work, consider brown corundum at 220 grit.
When should I use silicon carbide instead of aluminum oxide?
Silicon carbide is harder and cuts faster — use it when aluminum oxide is too slow: hard steel, stainless steel, ceramic, and glass. It costs more per pound but removes material faster, so the cost per job can actually be lower on hard surfaces. Aluminum oxide is better for softer materials and when you want less aggressive cutting.
Is silicon carbide reusable?
Silicon carbide fractures into sharp fragments during use, so it actually gets sharper as it breaks down (unlike aluminum oxide which rounds off). However, the particles become smaller with each use. Expect 2-3 reuse cycles before the particle size becomes too fine for effective blasting.
Quick Setup Guide
Load media into your sandblaster hopper. 100 grit is a medium-coarse abrasive suitable for moderate rust removal, paint stripping, and surface profiling. Set blaster pressure to 80-100 PSI for steel and iron, reduce to 60-80 PSI for softer metals like aluminum. Maintain 4-6 inch standoff distance for aggressive work, 8-12 inches for lighter finishing. Silicon carbide is harder than aluminum oxide and cuts faster but is more expensive per use — ideal for jobs where speed matters more than media cost.
