High-Temp Zirconia Ceramic Grinding Balls – Precision & Durability Redefined
Ultra-smooth zirconia ceramic balls engineered for extreme conditions, featuring 95%+ purity with near-zero porosity for unmatched wear resistance. Perfectly spherical with sub-micron surface finish (Ra<0.05μm), minimizing friction in high-speed bearings and precision grinding applications. Stable up to 800°C without thermal expansion cracks, ideal for aerospace, chemical reactors, and medical implant polishing. 5x harder than steel yet 40% lighter, reducing equipment wear while maintaining impact strength (15 GPa Vickers hardness). FDA-compliant material ensures corrosion-free performance in food processing and pharmaceutical industries. Batch-tested for consistent size tolerance (±0.001mm) – essential for lab equipment and semiconductor manufacturing. Cost-efficient bulk packs available for industrial buyers, with guaranteed 2-year performance warranty.
