Silicon Carbide Sandpaper

Silicon carbide sandpaper is a widely-used abrasive in woodworking, metalworking and automotive repair. It provides effective removal of stock material while simultaneously smoothing rough surfaces for staining or painting applications.

Aluminium oxide offers great heat resistance, helping prevent thermal degradation during intensive sanding processes. But how does it compare with plastic-coated aluminum oxide?


Silicon carbide abrasives boast higher hardness ratings than aluminum oxide or other types of sandpaper, giving it the power to cut quickly through materials even with light pressure applied on their belt or disc abrasives.

It can be used across a range of applications and materials, from metal, plastic and wood. Additionally, it can remove rust, paint and other coatings from surfaces as well as deburr metal surfaces or deburr metal as needed.

Silicon carbide grains have razor-sharp edges that can easily cut through glass, marble, cork, plastic and medium density fiberboard with light pressure; however, their effectiveness against harder materials like metal or hardwood is diminished.

Silicon carbide abrasives remain sharp for an extended period, providing predictable results with precision throughout the sanding process. Aluminum oxide abrasives may become less sharp over time due to grit deterioration and are therefore less effective on soft materials such as wood.

Heat Resistance

Silicon carbide sandpaper stands out due to its outstanding heat resistance, making it perfect for use on hard and tough surfaces. This property allows the material to maintain sharp cutting edges over an extended period of use while helping prevent clogging or burning of project materials. Furthermore, its high hardness decreases frictional heat levels while increasing friability.

DIY enthusiasts rely on this type of sandpaper as an indispensable tool, using it for everything from drywall sanding and prep for painting or varnishing wood furniture, refinishing antiques, preparing wood furniture for painting or varnishing, preparing antiques for painting and varnishing, to marine applications where its waterproof variants offer professional results.

Silicon carbide sandpaper is composed of silicon carbide mineral particles coated onto flexible backing materials like paper or cloth, using resin-based adhesive. Grit sizes for silicon carbide sandpaper are indicated with letters or numbers; higher numbers denote coarser grit sizes designed for rapid material removal.

Abrasive Power

Silicon carbide grains that compose sandpaper grit are harder and sharper than aluminum oxide grains, creating new edges more efficiently as they fragment. As such, this type of sandpaper works effectively for both stripping away old finishes from metal or wood as well as between coats of finish or paint application.

Silicon carbide sandpaper stands out from its competition by remaining resistant to grit deterioration with repeated use, providing consistent and predictable results that make surface preparation work a great deal simpler and more precise. Precision is essential when working on projects requiring surface preparation work.

Sandpaper with silicon carbide can easily cut through cork, glass, plastic and medium-density fiberboard under light pressure, while it also cuts rust from metal surfaces by removing oxidation and old finishes. In addition, its grits prepare surfaces for staining or painting. Due to this versatility it makes this an excellent choice for numerous applications ranging from coarse material removal to fine finishing touches.


Silicon carbide sandpaper is an extremely versatile sanding option, suitable for many projects of various types. Thanks to its hard surface and speedy removal of materials quickly and efficiently, making it the go-to choice for rough sanding projects as well as for stripping paint from surfaces.

Sandpaper stands the test of time compared to other abrasives, cutting down costs over the long-run and helping reduce costs associated with sanding. Friability also extends its lifespan as grains break down to form new sharp edges extending its lifespan further.

Silicon carbide sandpaper offers a more refined sanding experience compared to aluminum oxide and garnet, offering greater precision, finer grits, and greater precision, making it the ideal choice for delicate tasks like veneer or hardwood sanding. 2Sand offers silicon carbide in extra coarse, fine and micro finishing grit sizes available by the sheet or sleeves (available 5, 10, or 50 sleeves at once).
