Description
Our Custom Sapphire Glass Sheets are precision-engineered for demanding optical and industrial applications. Manufactured from high-purity, single-crystal sapphire, these sheets deliver exceptional Mohs 9 hardness—second only to diamond—offering outstanding scratch resistance and durability. They provide excellent transmission from UV to mid-infrared, making them ideal for optical windows, sensor covers, watch crystals, and high-end electronic components.
We specialize in full customization: size, thickness, shape (round, rectangular, or complex profiles), surface polish, edge finish, and tight tolerances to meet your exact specifications. Whether you need rapid prototyping or volume production, our CNC machining and double-side polishing capabilities ensure consistent quality. Backed by fast lead times and low MOQ options, we support your project from design to delivery. Contact us for a tailored quote.
The main characteristics of sapphire glass
The main characteristics of sapphire include high hardness, high scratch resistance, high transparency, high temperature resistance, etc., so it is widely used in many high-end applications.
- Scratch resistance: sapphire glass is made of artificial sapphire crystal, with extremely high hardness, can resist scratches and wear in daily useto maintain the clarity and gloss of the glass surface.
- Transparency and optical performance: sapphire glass crystal has a high degree of transparencyand can transmit more light, so that it has a wide range of applications in the field of observation and display. Transmittance band: 185 ~ 5000nm
- High temperature resistance: the melting point of sapphire glass is 2045°C, and the application temperature is generally below 2000°C.
- Pressure resistance: As a kind of high-strength glass, the compressive strength of sapphire glass at room temperature can reach 2.1GPa, so it is used as a viewing window in deep sea diving.
