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.

Except for sapphire glass, if you need another watch part, please contact me.Welcome to long-term cooperation.

Synthetic sapphire (Corundum or Al₂O₃) single crystal is a highly trusted material with its excellent chemical stability, mechanical property, and light transmission. It is often used in aggressive environments where reliability, optical transmission and strength are required.

Applications of Synthetic Sapphire

• UV and IR Optics - often used as infrared filters in military and industrial applications
• Watch glasses, watch crystals, and gauge
• Silicon on sapphire wafers; Superconductor substrate
• High temperature and pressure windows, or where corrosion resistance and abrasion resistance are required
• Electrical insulators
• Thin film deposition
• Transparent electronic substrate

Properties of Synthetic Sapphire

Synthetic sapphire is the hardest of all known oxide crystals with a 9 on the Mohs scale. Synthetic sapphire is second in hardness only to diamond, and retains its high strength at high temperatures. Synthetic sapphire crystals have good thermal properties, with excellent electrical and dielectric properties. In addition, synthetic sapphire combines zero porosity with near total resistance to acids and alkaline substances. Synthetic sapphire is insoluble in watch, and only reacts with hydrofluoric acid, phosphoric acid and potassium hydroxide at high temperature of above 300 degree Celsius.

Stanford Materials has been a provider of many kinds of synthetic sapphires, including sapphire wafers, sapphire lenses, sapphire substrates, watch glasses, and sapphire boule for many years. Synthetic sapphire is anisotropic hexagonal crystal. Its properties depend on crystallographic direction (relative to the optical C-axis). Our synthetic sapphire wafers are generated using the latest technology to maximize quality and transmittance. Because of our product’s quality, you can trust that it is your best choice for a variety of demanding applications.
