Silicon carbide in electric vehicles stands for more efficiency, higher power density and performance. Particularly with an 800 V battery system and a large battery capacity, silicon carbide leads to a higher efficiency in inverters and thus enables longer ranges or lower battery costs.

What Are the Right Abrasives for Your Metal Removal …

Silicon Carbide Silicon carbide crystals are hard, thin and very sharp—in fact, the only materials harder than silicon carbide are diamond and cubic boron nitride. Unfortunately, silicon carbide’s hardness and shape make it brittle, so even though it cuts quickly, it also tends to break down a bit faster than other abrasives, especially under extreme forces.
