Alumina Ceramic The Ultimate Material For High-End Manufacturing In Electronics Industrial And Medical Applications

The alumina ceramic fixing bracket base is made of high-purity (96%-99.9%) Al₂O₃ material, designed for high-stability, corrosion-resistant, and insulated applications. It features ultra-high hardness (Mohs 9), low thermal expansion coefficient (7-8×10⁻⁶/℃), and excellent chemical corrosion resistance, making it ideal for fixing and support needs in semiconductor, laser equipment, precision instruments, and more.

Primary Applications

• Precision Instruments: Optical platform brackets, sensor mounting bases

• Semiconductor Equipment: Vacuum chamber supports, wafer transfer rail bases

• Industrial Machinery: High-temperature furnace supports, automated equipment positioning bases

• Medical Devices: Imaging system fixtures, surgical instrument support tables

• Energy Sector: Fuel cell stack supports, high-voltage insulation mounts

Key Advantages

✅ Ultra-High Rigidity: Flexural strength ≥300MPa, no deformation under long-term load
✅ Extreme Environment Resistance: Stable performance from -60℃ to 1600℃, resistant to acids and alkalis
✅ Insulation & Anti-Static: Volume resistivity >10¹⁴Ω·cm, eliminates electromagnetic interference
✅ Precision Compatibility: Supports ±0.01mm dimensional tolerance customization
✅ Lightweight Design: Density 3.8g/cm³, 40% lighter than metal
