Lower Hardness (~60-100 HB) – Prone to faster wear than hardened steel or ceramic balls.
Oxidation Resistance – Naturally forms a protective oxide layer, but prolonged exposure to acidic/alkaline slurries may degrade performance.
Impact Resistance – Less durable than steel, leading to deformation or chipping in high-impact milling.
