85% - 99% Transmissivity Synthetic Sapphire Glass H9/HV1800-2200 Hardness
What is Sapphire:
Sapphire's attributes include high mechanical strength, temperature stability, wear resistance and chemical inertness. As a result, a Sapphire Rod will exceed other optical materials in harsh environments, providing a barrier between elements. Sapphire Rods are used commonly in optical and mechanical applications. We offering includes a wide range of Sapphire Rods stock parts and also we are welcome customization sapphire Rods.
Key Features Of Synthetic Sapphire:
1. Excellent Moh's Hardness Upto 9H, Only Softer Than Diamond(10H)
2. Great Transmittance From 200nm~5000nm; AVG>85% @ Visible Light Freqency
3. No Attacked By Acid Or Alkalis, Only Attacked By HF At 300℃.
4. High Softening Point, Low Thermal Expansion.
5. Excellent Mechnical Properties.
Sapphire crystals in a variety of sizes and sizes can be customized and can be customized with other special processes.Sapphire glass has tensile strength and can withstand high temperatures.Can be customized for various color graphic coatingsWhich makes this material ideal for use in hostile environments with its unique combination of excellent physical, chemical, and optical properties retaining its high strength at elevated temperatures. Resists attack from acids and alkali. Available as windows, lenses, prisms, blanks and tubing, all custom manufactured.

glasssurface technologypolishing ,chamfermiddle height random.contace me if you have other specific needsThese round sapphire
glass crystals come in a variety of thicknesses and diameters, are nearly unbreakable crystals making them highly prized by
watchmakers. These watch crystals can be glued into most watch cases or pressure fit into most plastic watch crystal gaskets. Each
sapphire watch crystal comes with a slightly polished bevel edge to give the watch crystal a nice finished look once it has been
installed. These generic sapphire glass crystals can be used to replace the watch crystals of almost every name brand watch
popular today, especially high-end watch crystals like those in Rolex watches, saving you both time and money.
