Why Use Silicon Carbide?
Silicon carbide is the hardest common abrasive grain with exception of diamond. Because it is tougher and sharper than aluminium oxide, even though it tends to wear down more quickly, it is still a long-lasting product that works well for polishing, harder materials, and uneven surfaces. It is the only grain that works well on glass, stone, and marble and is especially useful for metals, especially the tougher kinds, while also suitable for cork and MDF as well.Silicon carbide is widely used in wet sanding applications, including automotive polishing and the polishing of stone and marble. This works well in coarser grits for deburring metal and glass, rust removal, and refinishing wood floors (cutting through/removing earlier finishes). It is standard practice to use aluminium oxide for rough sanding raw wood and move to silicon carbide for finishing phases of the same job since it may also be used to sand in between finishing coatings in woodworking projects.
As an abrasive it is a somewhat adaptable and forgiving material that may be used in power and manual sanding applications, in the form of, among others, belts, discs, sheets, and sponges.
