Ultra Thin Sapphire Glass Discs / Shaped Plates / Sheets For Custom Fabrication

Ultra Thin Sapphire Glass Discs

The hardness of sapphire glass is extremely high reaching Mohs 9. Its strength will be better, so it can be used to make ultra-thin sapphire glass discs/plates/sheets. Our company can produce sapphire discs within a minimum thickness of 0.05mm. If the size is smaller, the thickness can also be made thinner. The thinner the sapphire sheet, the greater the transmittance of light. To achieve the best results in the light transmittance experiment. The thinner the sapphire piece, the longer it takes to polish, so the required cost is higher.

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.

1. 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.
2. 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
3. High temperature resistance: the melting point of sapphire glass is 2045°C, and the application temperature is generally below 2000°C.
4. 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.
