CarbiPro Silicon Carbide Abrasive Grinding Paper

Metallographic Silicon Carbide (SiC) Grinding Paper

CarbiPro silicon carbide (SiC) grinding paper is engineered for consistent, repeatable metallographic sample preparation across a wide range of materials. Our SiC abrasive papers are produced using controlled coating processes to deliver predictable material removal, uniform scratch patterns, and excellent disc-to-disc consistency.

CarbiPro SiC grinding paper is available in 8 in (200 mm), 10 in (250 mm), and 12 in (300 mm) diameters with PSA (adhesive) or plain paper backing, making it compatible with most manual and semi-automated grinding systems. Coarse and intermediate grits from 60/P60 through 600/P1200 are electrostatically coated to promote aggressive cutting and even abrasive distribution. Fine grits from 800/P2400 through 1200/P4000 are slurry coated, providing improved abrasive retention and enhanced control during high-precision grinding steps.

These SiC grinding papers are commonly used for the preparation of steels, aluminum alloys, copper alloys, cast irons, ceramics, and other engineering materials in quality control laboratories, universities, and research facilities. When used in a controlled grinding sequence, CarbiPro papers provide a reliable foundation for subsequent polishing operations.

All OnPoint Abrasives SiC grinding papers are stocked for fast shipment and supported by transparent pricing, volume discounts, and knowledgeable technical assistance to help laboratories reduce preparation costs without compromising results.

✅ FAQ – Silicon Carbide (SiC) Grinding Paper

What is silicon carbide (SiC) grinding paper used for in metallography?

Silicon carbide (SiC) grinding paper is used for planar grinding and material removal during the early stages of metallographic sample preparation. It is suitable for a wide range of materials, including steels, aluminum alloys, copper alloys, cast irons, and ceramics.

What is the difference between electrostatically coated and slurry-coated SiC papers?

Electrostatically coated SiC grinding papers (60–600 grit) orient abrasive particles upright for aggressive, uniform cutting during coarse and intermediate grinding.
Slurry-coated SiC grinding papers (800–1200 grit) provide improved abrasive retention and finer material removal control, making them better suited for high-precision grinding prior to polishing.

When should I use PSA-backed versus plain back grinding paper?

PSA-backed SiC grinding paper is recommended when fast disc changes and secure platen attachment are required, such as in high-throughput or production environments.
Plain back SiC grinding paper is preferred when using mechanical clamps, magnetic fixtures, or manual setups where adhesive backing is unnecessary or undesirable.

Which grit size should I start with for metallographic grinding?

The starting grit depends on the material and initial surface condition. Coarse grits (60–120) are typically used for heavy material removal or roughly cut surfaces, while intermediate grits (240–600) refine the surface before transitioning to fine grinding and polishing steps.

Are your SiC grinding papers compatible with standard grinding systems?

Yes. OnPoint Abrasives SiC grinding paper discs are available in 8″, 10″, and 12″ diameters and are compatible with most standard manual, semi-automated, and automated metallographic grinding systems.

Do slurry-coated SiC papers replace polishing steps?

No. Slurry-coated fine SiC grinding papers (800–1200 grit) improve surface control and scratch uniformity but are still part of the grinding process. Final surface finish and microstructural clarity are achieved during subsequent polishing steps using diamond or oxide suspensions.
