There are so many types of silicon carbide used in casting – I actually didn’t know any of them!

Casting is a metallurgical technique that was developed after steelmaking; it is simpler and less costly compared to steelmaking, which is why casting has become a popular manufacturing process nowadays. Silicon carbide used in casting is a type of silicon carbide product designed for use in casting processes. Silicon carbide finds extensive application in casting, and its role is extremely important! Not all types of silicon carbide suitable for casting can be used as casting materials. To produce high-quality cast iron, it is necessary to select the appropriate type of silicon carbide based on the production requirements. Generally, grades 70, 88, and 90 are commonly used for this purpose. During casting, these grades of silicon carbide play a positive role by facilitating chemical reactions among various elements; they also improve the flow properties of the molten iron and help prevent blockages at the outlets. Silicon carbide is an essential raw material in the casting process!
