This high-precision alumina ceramic ring component (purity ≥95%) is manufactured using isostatic pressing technology, featuring an ivory-white porcelain luster with a precision structure consisting of an annular body and symmetrically distributed grooves. Sintered at 1600°C, the product achieves a density of 3.85g/cm³ with surface roughness Ra≤0.4μm. Rounded edge treatment ensures installation safety, making it suitable for core transmission systems in automation equipment.
[Core Applications]
Precision Machinery: High-speed motor bearing retainers, servo system positioning rings
Electronic Semiconductors: IC test fixture insulation bases, wafer carrier positioning components
New Energy Sector: Lithium battery pole piece cutting dies, hydrogen fuel cell bipolar plate frames
Use dedicated ceramic clamping tools during installation to prevent impact damage
Control temperature changes to ≤5℃/min in working environment
Clean with anhydrous ethanol ultrasonic cleaning (power ≤40kHz)
Avoid storage with metal hard objects; use anti-static packaging
[After-Sales Service]
✓ 7-day no-reason return policy (unopened products) ✓ Free replacement for non-human damage within 1-year warranty ✓ Customization service available (MOQ 50 pieces) ✓ Third-party material testing reports (SGS/CTI optional)
