Black silicon carbide grit is one of the most popularly used abrasives for use in rock tumblers, boasting an Mohs scale hardness of 9.1. Only diamond and boron carbide grits surpass this material’s hardness rating. This makes them perfect for smoothening rough rocks to an elegant surface finish, particularly when used in combination with aluminum oxide abrasives. Hardness Black silicon carbide abrasives are often considered one of the hardest materials available for use, second only to diamond and boron carbide abrasives. Due to its exceptional hardness and durability, these materials make for great tools when used to tumble and polish different materials like glass, metal, and gemstones. Black silicon carbide […]

There are various types of abrasives used for grinding and cutting materials. Depending on what material needs to be ground, different grit sizes will best meet its demands. Simple steels without high carbon content typically grind well on natural (Arkansas) stones or aluminum oxide stones, while those containing hard carbides will slow down considerably when using aluminum oxide stones. Sharpening Knives Silicon carbide grinding stones, also referred to as whetstones or sharpening stones, help knife blades and tools maintain robust cutting edges. These stones often cut faster than aluminum oxide grinding stones while needing less pressure for sharpening edges. These fast-cutting stones can be used for quickly sharpening blade edges,

Silicon carbide is one of the strongest advanced ceramic materials. Due to its superior strength, rigidity, low thermal expansion and corrosion resistance properties, silicon carbide makes an excellent material choice for automobile brakes and clutches as well as bulletproof vests. Silicon carbide is one of the hardest materials, second only to boron carbide and diamond. It is often chosen as an option for use in refractory castables and abrasives. Hardness Silicon carbide is one of the hardest substances currently known, rivaling hard materials like diamond and boron carbide in terms of hardness. Because of this, silicon carbide is widely used in making weapons and armor plates. High strength and creep

Silicon carbide semiconductors have the potential to transform multiple markets. But what makes them special? Power devices crafted from silicon carbide offer numerous advantages when it comes to quality, reliability and efficiency.
