Ceramic balls are widely used in precision bearings, medical devices, aerospace, automotive, and high-temperature corrosion-resistant equipment. Ceramic balls made from different materials exhibit significant differences in core properties such as hardness, density, temperature resistance, and corrosion resistance. Below is a comparison table of the parameters for four mainstream ceramic ball types to assist with product selection.   Parameter Zirconia Ceramic Balls Alumina Ceramic Balls Silicon Carbide Ceramic Silicon Nitride Ceramic Balls Product Image Appearance Milky white/beige High-gloss, fine surface Extremely high surface finish Pure white   Hard texture   Neat and uniform appearance Blackish-gray   Matte finish   Dense and compact texture Grayish-black Smooth   matte finish   Precision-polished, burr-free   Density（g/cm³） 6.05 3.9 3.2 3.25 Rockwell Hardness（HRA） 89-90 88-89 92-93 91-92 High-Temperature Resistance (°C) 1000°C 1200°C 1600°C 1300°C Compressive Strength（MPa） 2000 1800 2200 2100 Corrosion Resistance Resistant to acids and alkalis Corrosion-resistant   Excellent aging resistance Resistant to weak acids and alkalis   Use with caution in strong acid and alkali environments Extremely high corrosion resistance   Resistant to strong acids and alkalis   Resistant to solvent erosion Superior corrosion resistance   Suitable for various harsh chemical environments   Insulation Properties High insulation   Non-conductive   Anti-static Ultra-high insulation   Stable electrical performance Semi-insulating   Weak electrical conductivity High insulation   High-temperature resistance without electrical leakage   Key Features Excellent toughness   Resistant to chipping and cracking   High surface finish   Wear-resistant and quiet   high precision High cost-effectiveness   sufficient hardness   good insulation   high-temperature and oxidation resistance   uniform texture   extremely versatile Ultra-hard and ultra-wear-resistant   ultra-high temperature resistance   superior corrosion resistance   low coefficient of friction   resistant to high temperatures and pressures   extremely long service life High toughness   thermal shock resistance   resistance to alternating high and low temperatures   wear and fatigue resistance   lightweight   resistant to heat buildup and damage during high-speed operation Major Application Industries Precision bearings   Medical devices   Food processing machinery   Valves and valve cores   Electronic equipment   Precision Instruments   High-Speed Transmission Components Chemical Packing   Grinding and Polishing   Hardware Components   Seals   Standard Bearings   Home Appliance Components   Water Treatment Equipment High-Temperature Equipment   Chemical Corrosion-Resistant Equipment   Aerospace   Metallurgical Machinery   High-Pressure Wear-Resistant   Components for Extreme Operating Conditions High-Speed Precision Bearings   Wind Power Equipment   Automotive Precision Components   Aerospace   High-Temperature Power Equipment   Please contact customer service for details on custom colors.   If you have a need for custom precision ceramic balls, please provide the specified dimensions, tolerances, and operating conditions.
