Product Description
Precision Sapphire Lift Pins Single Crystal Al₂O₃ Wear Resistant for High-Accuracy Wafer Positioning
Sapphire lift pins are precision mechanical components manufactured from high-purity single-crystal sapphire, engineered for high-precision positioning, high-temperature resistance, and wear-intensive applications. ZMSH provides full-parameter customization services (including diameter, length, surface roughness, and crystallographic orientation optimization), supporting rapid small-batch delivery to meet the extreme performance demands of semiconductor, medical, aerospace, and industrial sectors.
Key Characteristics
1. Ultra-high Mechanical Strength: With a compressive strength exceeding 300,000 psi, these pins withstand high-frequency lifting loads (e.g., 12-inch wafer handling systems in semiconductor fabrication).
2. High-Temperature Stability: Operate continuously at 1,500°C and tolerate short-term exposure up to 2,050°C (ideal for laser welding or combustion chamber positioning).
3. Low Friction Coefficient: Post-polishing friction coefficients <0.15 minimize energy loss during precision motion (e.g., lithography stage adjustments).
4. Chemical Inertness: Resistant to strong acids, alkalis, and organic solvents, suitable for cleanrooms and semiconductor etching environments.
