Lower Density (2.7 g/cm³) – Lighter than steel (7.8 g/cm³) or ceramic balls, reducing energy consumption in ball mills.

Softer Material – Less aggressive grinding compared to steel or zirconia, making them suitable for delicate materials (e.g., food, pigments, cosmetics).

Moderate Wear Resistance – Not ideal for extremely hard materials (e.g., metals, minerals) but effective for softer powders.
