Silicon Carbide Grinding Media Balls

Silicon carbide grinding media ball has unique features such as high strength, good wear/corrosion/chemical resistance, light weight, low thermal expansion, high temperature resistance, electrical insulation and non-magnetic. It is perfect for grinding application which requires high temperature, high hardness and minimized contamination, such as semiconductor and electronic coating. Its high hardness can meet the vast majority of metal powder crushing and refining. They are extensively applied to in the fields of Metallurgy, Ceramics, Electronics, Light Industry, Paint, Medicine, Geology, Chemical Engineering and so on. Choose between 3 mm - 25 mm in size for the silicon carbide media.
