Black Silicon Carbide Black Carborundum

Black silicon carbide (black carborundum) is black color and its microscopic shape is hexagonal crystal. The Mohs hardness of silicon carbide is 9.2, the microhardness is 3000--3300 kg/mm 2 , the hardness is 2670-2815 kg/mm, and the microhardness is 3300 kg per Cubic millimeters. The density is generally considered to be 3.20 g/mm 3 , and the natural bulk density of the silicon carbide abrasive is between 1.2 and 1.6 g/mm 3 and the specific gravity is 3.20 to 3.25. The grit number include #12.#14.#16.#20.#22.#24.#30.#36.#46.#60.#80.#90.#100.#120.#150.#180.#240.#280. #320, #360, #400, #500, #600, #700, #800, #1000, #1200, #1500, #2000, #2500, #3000, #4000, #5000, #6000, #8000, #10000, It is mainly used for hardness alloys, titanium alloys, stainless steel, copper, aluminum, zinc, ceramics, stone, agate, Grinding and polishing of jade, fine jewelry, electronic components and other materials. Not only can you make abrasive tools and advanced refractory materials.
