Precisely Processed Small Size of Sapphire Glass Parts

Sapphire Glass Parts & Components

Sapphire glass is a kind of glass material with high hardness, high scratch resistance and high light transmission, which is widely used in the customization of optical glass. Due to the high cost of sapphire glass materials, it is generally used in high-end precision machining fields. The difficulty of processing sapphire glass parts is higher than other glass materials. Because of its Mohs hardness of 9, it is easy to crack during CNC cutting. In order to avoid cracking as much as possible, the speed of the cutting must be slowed down during machining , which also leads to longer processing times and higher costs for sapphire glass.

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.
