Black Silicon Carbide Sizes Range: Precision-Graded for Diverse Industrial Applications
Black silicon carbide, renowned for its high hardness, thermal stability, and exceptional abrasive properties, is available in a comprehensive range of sizes to meet the specific needs of various industries. Below is a detailed overview of our standardized size classifications, designed to ensure optimal performance in applications from grinding and polishing to blasting and refractories.
1. Granular Sizes: Coarse to Medium Grades
Ideal for heavy-duty abrasive tasks and structural applications, our granular black silicon carbide is graded to balance cutting efficiency with material durability.
- Coarse Granules (16#–46#):
- 16# / 1180μm: Suited for rough grinding of metals, ceramics, and stone, such as shaping granite slabs or deburring cast iron components.
- 24# / 850μm: Commonly used in sandblasting equipment for removing rust, paint, or scale from large surfaces (e.g., ship hulls, steel structures).
- 36# / 600μm & 46# / 425μm: Effective in wheel abrasives for foundry work and metal blank processing, offering a balance between material removal rate and surface finish.
- Medium Granules (60#–100#):
- 60# / 250μm & 80# / 180μm: Perfect for precision grinding of tools (e.g., drills, saw blades) and preparing surfaces for plating or coating.
- 100# / 150μm: Used in bonded abrasives for woodworking and in the production of abrasive paper for medium-finish sanding.
2. Powder Sizes: Fine to Ultra-Fine Grades
Engineered for applications requiring (fine) particle control, such as lapping, polishing, and high-tech manufacturing.
- Fine Powders (120#–325#):
- 120# / 125μm & 150# / 106μm: Used in lapping compounds for precision components like bearings, seals, and optical lenses.
- 220# / 63μm & 240# / 53μm: Suitable for polishing non-ferrous metals and ceramics to achieve a smooth, matte finish.
- 325# / 45μm: Critical in the production of grinding wheels for super-finishing and in abrasive slurries for semiconductor wafer processing.
- Ultra-Fine Powders (Micron Sizes):
- Micron 25 / 25μm & Micron 15 / 15μm: Used in high-precision lapping of magnetic heads, carbide tools, and medical implants.
- Micron 10 / 10μm & Micron 5 / 5μm: Ideal for polishing optical glass, gemstones, and microelectronic components to a mirror-like surface.
- Micron 1 / 1μm & Below: Employed in advanced ceramic sintering and as a reinforcing filler in composite materials for aerospace and automotive industries.
