Silicon Carbide Grinding Stone

Grinding stones are essential tools in many projects. Available in various structures to meet individual application needs, these grinding stones come in handy and should never be underestimated as an indispensable asset in the toolbox.

Green silicon carbide abrasive is one of the most frequently used in grinding wheels, as it features hard and brittle properties with excellent thermal conductivity and low thermal expansion rates.

High Hardness

Silicon carbide (SiC), commonly used as an abrasive material, is an inorganic chemical compound containing silicon and carbon. Although naturally present as moissanite mineral, SiC has been mass produced since 1893 for use as grinding powders or blasting media.

Green silicon carbide grinding stones have an incredible hardness that makes them highly effective at heavy-duty grinding applications, including metal like aluminum oxide. Furthermore, their versatile nature enables them to handle grinding of tough and brittle materials such as glass, stone and ceramics with different hardnesses and toughnesses as well as low tensile strength materials of various hardnesses and toughness.

Hardness of stone surfaces is crucial when it comes to grinding; its hardness determines how easily they cut through material. A SiC stone is much harder than an aluminum oxide one and will therefore enable faster, more precise finishing processes and provide extra wear resistance that aluminum oxide or natural rocks might lack. Additionally, SiC stones may be ideal for grinding soft steels like D2, which require extra wear resistance that aluminum oxide or natural rocks may lack.

Excellent Sharpness

Silicon Carbide (SiC) is an ultrahard ceramic material, second only to diamond and cubic boron nitride in terms of hardness. Additionally, it boasts excellent toughness properties and is capable of withstanding extreme temperatures; for this reason it’s used extensively in grinding stones, drill bits, and many other abrasive products.

Green silicon carbide is an excellent material choice for general purpose grinding applications, particularly those working with steel and ferritic cast irons. Its tougher properties mean it will not easily fracture when exposed to impact or vibration when grinding, providing greater productivity than aluminum oxide does.

Green silicon carbide stones come with either vitrified, which resembles glass, or resinoid bonds that contain an organic substance such as resin as their basis for holding together their abrasive grains. The type of bond determines both its performance and suitability for applications; vitrified stones tend to perform better for precision grinding while resinoid ones work well when grinding rough materials. No matter its bond type, all stones should be regularly lubricated with water during use to avoid damage while simultaneously creating consistent grinding action.

Long Lifespan

Manufacturing industries rely heavily on abrasives as an indispensable component. From smoothing welds on construction sites to grinding crankshafts, they serve an invaluable purpose within this sector of industry.

Green silicon carbide (SiC) stands out amongst all available abrasives as being particularly impressive due to its durability and performance, not to mention being cost-effective enough to be used in any workplace environment.

This type of abrasive is composed of silicon and carbon heated in electric resistance furnaces to produce hard, friable grains suitable for grinding metals.

SiC grain outshines aluminum oxide, which quickly dulls and lacks the longevity of other abrasives such as diamond and cubic boron nitride (CBN). Furthermore, SiC can even be used to grind metals that contain hard carbides like chromium carbides or vanadium carbides which would otherwise be difficult to grind using an aluminum oxide stone; it can even be used on metals containing hard carbides like vanadium carbides that would be very challenging with aluminum oxide stones alone! However, this stone should never be used on hard abrasives such as diamond or CBN as these require special protection to avoid damage!


Green silicon carbide grinding stones are durable abrasives suitable for heavy-duty grinding applications, from glass cutting to refinishing wood flooring refinishing. Their sharp edge makes them effective at performing various grinding tasks; from cutting glass to refinishing flooring. Furthermore, these safe stones require minimal maintenance requirements and maintenance costs.

Aluminum oxide abrasives are ideal for grinding nonmetallic materials like glass, plastic and medium density fiberboard, while also being capable of grinding low tensile metals such as aluminum and bronze with lower tensile strengths. While other abrasives may work on metal grinding jobs as well, aluminum oxide ones tend to be more resilient due to larger, more resilient grains and the ability to handle greater pressure levels.

To achieve optimal results, begin with aluminum oxide abrasives for rough sanding before switching to silicon carbide fine sanding – this will create a seamless surface finish without lippage or marring. Before using green silicon carbide wheels on an angle grinder, ensure they are securely attached; referring to its owner’s manual will assist here. Once this wheel is secure, apply light pressure against its disk while moving in circular movements across your floor surface.


Green silicon carbide grinding stones feature tougher than aluminum oxide points and have razor-sharp abrasive grains for efficient cutting of glass, plastics and medium density fiberboard with minimal pressure application. In addition, green silicon carbide stones can also grind marble, stone and refractory materials while being unsuited to metals or nonferrous alloys that react negatively with carbon.

Green silicon carbide offers greater impact resistance than black silicon carbide, but still wears faster when used to grind softer metals due to containing more hard carbide particles than simpler steels.

At its heart lies diamond, making it the optimal solution for grinding soft metals such as aluminum, bronze, and iron. Furthermore, its ability to withstand high temperatures during grinding makes it ideal for use on projects with a lot of stock to remove. Unfortunately, diamond and zirconia alumina tend to last longer abrasives like zirconia alumina due to their increased longevity compared to their narrower and brittle construction; similarly, tungsten carbide can withstand much higher temperatures for increased durability compared to tungsten carbide which cannot.
