Product Description
Sapphire Tubes Customized Tubular Components 99.999% Al₂O₃ 80%-90% Transmittance For Endoscopic Catheter
Sapphire tubes and customized tubular components are high-performance optical elements precision-engineered from single-crystal aluminum oxide (α-Al₂O₃). Distinct from standard circular tubing, these custom sapphire tubes can be fabricated with specialized cross-sections (square, hexagonal, D-shaped, etc.) while maintaining sapphire's intrinsic properties: ultra-high hardness (Mohs 9), broad-spectrum transmission (UV to IR wavelengths), and exceptional chemical stability. Their unique structural adaptability makes them ideal for specialized optical transmission, extreme-environment sealing, and fluid control systems, with critical applications in high-power lasers, semiconductor equipment, and high-temperature observation systems.
Key Characteristics
1. Complex Structural Customization:
· Supports asymmetric cross-sections (internal/external polygons,
tapered diameters, etc.) with inner diameter tolerances controlled
within ±0.05mm, meeting requirements for complex optical paths or
fluid channels.
2. Extreme Environmental Resistance:
· Withstands prolonged 800°C operation (short-term 1500°C
exposure), exhibits excellent thermal shock resistance (CTE:
5.3×10⁻⁶/°C), and resists strong acid/alkali corrosion (pH1-14),
making it suitable for chemical reactors or plasma processing
equipment.
3. Optical & Mechanical Performance:
· 80% transmittance from UV to mid-IR, with optional anti-reflection coatings (<1% reflectivity) on inner/outer walls
· Flexural strength >500MPa, maintaining structural integrity even at minimal wall thicknesses (0.5mm)
4. Sealing & Surface Properties:
· Internal/external surfaces polished to Ra≤10nm, capable of
high-vacuum sealing (leak rate <1×10⁻⁹ Pa·m³/s), meeting
cleanliness standards for semiconductor and laser systems.

FAQ
1. Q: What are the advantages of sapphire tubes compared to quartz
tubes?
A: Sapphire tubes offer 3x higher hardness (Mohs 9), 2x better
thermal conductivity (35W/m·K), and superior chemical resistance,
especially in extreme pH environments.
2. Q: Can sapphire tubes be customized for medical endoscope
applications?
A: Yes, we provide medical-grade sapphire tubes with <10nm
surface roughness (Ra), biocompatible certification (ISO 10993-5),
and precision inner diameters down to 0.3mm.
