Green Silicon Carbide Abrasives

Green silicon carbide is often used as grinding wheel and sandblasting.

Its grinding wheel is suitable for grinding materials with low tensile strength, such as gray cast iron, non-ferrous metal pure aluminum, aluminum alloy, brass, cupronickel, copper, etc. Viscosity comparison Large materials, as well as stone, ceramic glass, refractory materials, etc.

Its powder is green, crystal structure, high hardness, strong cutting ability, stable chemical properties, good thermal conductivity.

Green SIC production process: the production method of it is the same as that of Black silicon carbide, but the purity of the raw materials used is higher, and it is also formed at a high temperature of about 2200°C in a resistance furnace. It is green, translucent, and hexagonal, the SIC content is higher than that of black, and the physical properties are similar to Black SIC, but the performance is slightly more brittle than black, and it also has better thermal conductivity and semiconductor properties.

It is suitable for grinding hard alloys, hard and brittle metals and non-metallic materials, such as non-ferrous metals such as copper, brass, aluminum and magnesium, gemstones, optical glass, ceramics and other non-metallic materials, the green silicon carbide grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing.

Its grinding wheel applications include: grinding materials include cast iron, non-ferrous metals, mild steel, hard steel, 300 (or 400) series stainless steel, tools or high-speed steel, malleable cast steel, (AlNiCo) magnetic steel, Brass, chrome plate, etc.

The advantage of the Green silicon carbide grinding wheel is that the abrasive grains are sharp and the hardness is high, and it can grind hard and brittle materials such as cemented carbide, optical glass, ceramics, and alloys. Moreover, it has good thermal conductivity and is suitable for grinding workpieces that are easily deformed by heating. However, the green silicon carbide grinding wheel also has disadvantages, that is, its brittleness is relatively large, so it is poor in maintaining edges and corners, and it is not suitable for processing workpieces with high toughness.
