Customized Double Cylinder Sapphire Crystal Watch Glass for Wristwatch Parts Why Choose sapphire crystal? Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond. Because of its hardness (second only to Diamond), Sapphires are used in industrial applications such as components for watch crystals and movement bearings, scientific instruments, high-durability windows, and insulating substrates in special purpose solid state electronics Sapphire is grown using a variety of methods. Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method. Sapphire is able to be cut thinner than alternative crystals due to its structural durability. Sapphire crystals features: 1#Thinner and Stronger than Standard Glass Windows 2#Transmits Wavelengths Ranging From UV to Mid-Infrared 3#Features Extreme Surface Hardness and Chemical Resistance Chemical compositionAl2O3Density3.98gBending strength320-930PaVickrs hardness1800-2200Optical transmission&gt;90%Melting point2050℃Mohs hardness9(Next only to diamonds:10)Bevel0.1-0.5mmCoatingupon customer request Sapphire Crystal Application: 1. for high-class watches 2. for Led 3. for manufacturing equipment of semiconductors 4. for medical equipment 5. for beauty equipment 6. for jewelry pendant 7. other unique products FAQ: Q: How did you test the product before they are packed?A: We have strict QC procedure, each product will be tested by three times even more with professional machine before packing.Q: What if the products we received are not good?A: Contact us without hesitation, our special after-sales service will take the responsibility.
