Industry Applications
1. Electronics & Semiconductor Processing
Alumina ceramic rollers are widely used in wafer transport systems due to their ultra-high purity (99% Al₂O₃) and low-contaminating properties.
Semiconductor manufacturer replaced graphite rollers with alumina ceramics rollers, reducing particle contamination and extending maintenance intervals.
2. Automotive & Aerospace
Ceramic shafts and alumina ceramic cylinders serve as lightweight, high-strength components in fuel injection systems and sensor housings.
Performance Benefit: Withstands thermal cycling from -50°C to 1500°C without easy cracking or warping.
3. Chemical & Petrochemical
Ceramic sticks and rods are used in agitators and pump components, resisting acids, alkali, and abrasive slurry.
Chemical plants switch from stainless steel to alumina products, achieving a longer lifespan in sulfuric acid environments.
4. Textile & Printing
Alumina ceramic cylinders guide high-speed yarns with near-zero friction, minimizing fiber damage.
5. Food & Packaging Machinery
Ceramic shafts and rollers prevent corrosion from acidic/alkaline cleaning agents, extending service life. metal alternatives.
6. Medical Equipment
Ceramic sticks serve as non-magnetic, sterilizable probes in MRI-compatible devices.
Why Choose Alumina Ceramic Products?
✔ Longer Service Life – Reduces downtime and replacement costs.
✔ Corrosion-Proof – Ideal for acidic, alkaline, and high-moisture environments.
✔ Non-Magnetic & EMI-Resistant – Critical for medical and electronics applications.
✔ Custom Solutions – Tailored dimensions and tolerances.
