Silicon carbide is one of the hardest materials on Earth. Thanks to this incredible hardness, silicon carbide discs can withstand long hours of use in intense applications without breaking down or becoming damaged – giving users confidence in completing projects while saving money in replacements down the line.

These heavy-duty sanding discs feature heavy-duty vulcanized fiber backing with heat-resistant resins for heat resistance. Their resistance to loading and clogging enables them to cut through thick adhesive coatings such as epoxy, glue, sealant, urethane rubberized coatings and mastics with ease. Ideal for stone fabrication and glass deburring applications alike – available with 50 to 800 grit options!

These discs are ideal for removing rust and corrosion, prepping surfaces for paint prep, finishing woodwork and metal work, dry sanding E-coat, primer, and paint finishes, and dry sanding E-coat, primer, and paint finishes. Their open structured backing helps reduce clogging and dust accumulation with its pin hole pattern enabling easy vacuum attachment.

These discs, tailored specifically for various power sanders, make an excellent choice for grinding and smoothing concrete and masonry surfaces. By removing coatings, adhesives, and imperfections to produce an exquisite, flawless surface they also help shape and polish natural stones like granite and marble surfaces.

These sanding discs provide an economical alternative to more costly diamond grinding discs for users with limited budgets, yet do not offer the same level of longevity or precision compared to their more costly counterparts. Furthermore, they tend to clog more easily and need frequent cleaning/replacing thus decreasing effectiveness while increasing project completion time.

Silicon carbide’s unique properties make it a crucial material in many industries. Aerospace companies use silicon carbide components that withstand extreme temperatures and thermal shock to manufacture components that last. Semiconductor manufacturing utilizes it too for efficient heat dissipation purposes. Furthermore, academic institutions rely on silicon carbide powder research into new materials and technologies, furthering science and engineering towards social advancement.


Silicon carbide is an integral ceramic material with many applications. It is widely renowned for its exceptionally hard surface that rivals diamond and cubic boron nitride in hardness; production costs are relatively low, making this material even more cost-effective and durable than many others. These qualities make Silicon Carbide the ideal material to be used as an abrasive material when grinding, cutting and polishing are in process.

Silicon Carbide boasts superior corrosion resistance, making it suitable for acidic and oxidative environments, temperature extremes and strong mechanical stress. Due to being brittle material it may crack easily during use resulting in new sharp abrasive grains producing uniform scratch patterns.

Silicon carbide’s abrasive properties make it an invaluable material in industrial sanding processes. To use it effectively in this arena, typically the material is attached to cloth or resin backing before being pressed onto disc surface for pressing. Once produced, this sanding disc can be used to shape and smooth glass, stone, concrete, marble, granite and ceramic surfaces as well as nonmetallic surfaces such as fiberglass plastic and rubber surfaces.

Silicon carbide sanding discs are among the most frequently utilized tools in woodworking. Their applications range from removing old finishes or grime, to creating smooth surfaces ready for painting. When using sic sanding discs it is vitally important that safety guidelines are observed, such as wearing protective equipment and selecting an appropriate disc speed.

Silicon carbide sanding discs are popular choice among laboratories for precision work and experimentation, being highly effective at removing small amounts of material for smooth finishes while being known for their durability and longevity – this makes them popular among government agencies for aerospace engineering projects as well as materials science research. Silicon carbide also features excellent thermal conductivity as well as resistance against thermal shock. Additionally, these lightweight discs boast excellent thermal conductivity with exceptional resistance against thermal shock.


Silicon carbide is an extremely resilient material that can be used for various sanding and polishing tasks, from hardwood sanding and polishing, through aluminum polishing, brass finishing and natural stone surfaces such as granite marble travertine polishing. Available in various grit sizes to meet various applications; most power sanders support it.

Silicon Carbide Resin Fiber Discs These high-grade and heavy-duty abrasive pads are suitable for an array of industrial uses such as grinding metals, stone sanding and concrete deburring. Equipped with premium silicon carbide grains mounted on a durable vulcanized fiber backing for heat, glazing and loading resistance; 4-1/2″ and 5″ sizes come equipped with various grit options to suit a range of finishing tasks.

Silicon carbide stands out from other abrasives by cutting more quickly, which allows its pads to last longer while still producing excellent finishes. Furthermore, being brittle means there is less likelihood of damage being done during abrasion; many users will start their sanding with aluminum oxide abrasives before switching over to silicon carbide pads to achieve optimal results.

Ceramic, cubic zirconium and non-precious metal casting sprues can all benefit from grinding with moissanite, which also forms the gemstone moissanite found naturally. Most commonly though, it is produced as either powder or crystal form to be used as an abrasive.

Our high-grade PSA silicon carbide sanding discs are engineered to last while still producing exceptional finishes on multiple materials. Available in various grits for creating the ideal finish on any surface – wood, paint, fiberglass, terrazzo, marble and leather are just some of the many surfaces they can be used on! Also suitable for dry or wet sanding applications and contain anti-clog stearate to extend disc life!


Silicon carbide is one of the hardest materials, enabling these discs to withstand high levels of heat and pressure without becoming damaged or dulled by use. Furthermore, their sharp edge allows for faster material removal – ideal for applications that involve rapidly and effectively stripping paint, varnish, polyurethane coatings shellac or wood coatings off surfaces quickly and effectively.

Before beginning to sand, always ensure you wear proper safety equipment. This includes wearing a dust mask to shield yourself from harmful silica particles released when using disc sanders, choosing the proper grit size and speed recommended for your project and selecting appropriate disc speeds so as to get optimal results.

If you need a durable and sharp sanding disc that will stand up over time, look no further than Black Hawk Abrasives 5 inch silicon carbide resin fiber disc. Constructed with premium silicon carbide grains secured to heavy X-weight cloth backing via resin on resin bond for extra longevity, it’s ideal for removing paint, varnish, polyurethane coatings such as shellac or polyurethane polyurethane coatings such as shellac coating, concrete surfaces like marble and stone surfaces etc.

These high-performance sanding discs are ideal for any number of projects, from rough sanding to fine finishing. They’re suitable for use on fiberglass and plastic materials as well as metals like stainless steel. Plus they come with both coarse and fine grit options to accommodate different applications – perfect for removing adhesives from concrete or drywall!

Silicon carbide is produced by heating a mixture of silica and carbon in a furnace, before crushing into various-sized abrasive grains depending on the grit level of a sanding disc. Once crushed, these grains are attached securely to paper or cloth backing material with resin bonds so they remain attached even under extreme pressure and heat conditions.
