Silicon Carbide Black 90 mesh

Why Choose Black Silicon Carbide 90 Mesh?

Black silicon carbide is a synthetic mineral produced in electric resistance furnaces from silica sand and petroleum coke. The 90 mesh grade offers a controlled particle size distribution that balances fast stock removal with a uniform surface finish. It is harder than aluminum oxide, making it suitable for blasting tungsten carbide, titanium, hardened steels, and other challenging substrates.

This abrasive is widely used in pressure blasting, suction blasting, and wheel blasting systems. Its sharp, blocky grains fracture under impact, continuously exposing fresh cutting edges. This self-sharpening characteristic helps maintain a consistent blast pattern and reduces downtime for media changes.

Typical Applications

• Hard metal surface preparation: Removes mill scale, rust, and coatings from hardened steel components before welding or coating.
• Deburring and deflashing: Cleans sharp edges from machined or cast metal parts without excessive material removal.
• Non-slip surface profiling: Creates a uniform anchor profile on floors, stairs, and industrial walkways.
• Ceramic and glass etching: Provides a matte finish or frosted effect on glass, stone, and ceramic surfaces.
• Composite trimming: Used in aerospace and automotive sectors for trimming carbon fiber and fiberglass components.

Selection and Handling Tips

When selecting silicon carbide black 90 mesh, consider your blasting equipment type, nozzle size, and desired surface profile. This grade works well with 3/16-inch to 1/4-inch nozzle orifices at 80–100 PSI for most industrial blasting operations. Always sieve the media before reuse to remove fines and contaminants that can slow down cutting speed.

Store bags in a dry, covered area. Moisture absorption can cause clumping and disrupt media flow in blast pots. If you are unsure about the right grade for your substrate, our team can help you match the abrasive to your blasting parameters and finish requirements.
