Silicon Carbide Grinding Media Description
Silicon carbide balls are costly grinding media used for milling identical materials (silicon carbide ball for milling silicon carbide materials) to avoid contamination. SAM's silicon carbide grinding media are available in sizes of 5 mm, 10 mm, 12 mm, 15 mm and 20 mm. Custom sizes are also available.
