Silicon Carbide Black 120 mesh

Why Choose Black Silicon Carbide 120 Grit?

Black silicon carbide (SiC) is a man-made mineral produced in electric resistance furnaces from silica sand and petroleum coke. It is the hardest blasting abrasive commonly available, second only to diamond and boron carbide. The 120 mesh size is a fine, sharp powder that fractures easily, constantly exposing new, razor-sharp cutting edges. This self-sharpening characteristic makes it highly efficient for consistent, high-speed cutting action.

Industrial Applications for 120 Mesh SiC

The 120 grit size is specifically selected for tasks requiring a balance of material removal and surface finish. It is not a general-purpose heavy stripping grit but a precision tool for specific industrial processes.

• Precision Blasting: Ideal for micro-blasting and surface texturing of hard metals, carbides, and tool steels where tight dimensional tolerances must be maintained.
• Lapping and Grinding: Used as a loose abrasive for lapping valves, seals, and precision mechanical components to achieve a flat, smooth finish.
• Surface Preparation: Prepares hard metal surfaces for thermal spray coatings, brazing, or bonding by creating a clean, high-energy anchor profile.
• Ceramics and Stone: Effective for etching, finishing, and cutting hard, brittle materials like technical ceramics and granite.

Handling and Selection Guidance

Selecting the correct abrasive size is crucial for process efficiency. The 120 mesh is a fine powder and requires specific blasting equipment, typically suction or pressure blast cabinets with precise media flow controls. It is not recommended for wheel blasting machines. For optimal results, ensure your air supply is completely dry and oil-free to prevent clogging. Always conduct a small-scale test on a sample workpiece to confirm the surface finish meets your specification before full-scale production.
