Sapphire disc descriptionCustom Sapphire Disc Synthetic Sapphire Washer Polishing Bubble-Free Wear-Resistant

 
 

Custom Sapphire Disc Synthetic Sapphire Washer Polishing Bubble-Free Wear-Resistant

 
 

Sapphire washers are fabricated from single-crystal Al₂O₅, offering exceptional hardness, corrosion resistance, and thermal stability, making them ideal for sealing, insulation, and precision support in extreme environments.

 

Sapphire washers can be manufactured with larger outer and inner diameters to accommodate broader applications. Due to sapphire's inertness, they serve as excellent insulators. Moreover, the material's compressive strength enables it to withstand most operating conditions.

 

 

 

Sapphire disc propertiesCustom Sapphire Disc Synthetic Sapphire Washer Polishing Bubble-Free Wear-Resistant

 

- Ultra-High Hardness: Mohs hardness of 9 (second only to diamond), scratch-resistant.

 

- Chemical Corrosion Resistance: Resistant to strong acids/alkalis (except HF).

 

- High-Temperature Resistance: Operational up to 1800°C (short-term).

 

- Low Friction Coefficient: Surface polished to Ra < 0.01 μm, minimizing wear.

 

- Insulation Properties: Resistivity > 10¹⁴ Ω·cm.
