Product properities

1. High hardness: Sapphire tubes hardness is Mohs 9.0 which is sencond hardness only to the hardnest diamond, making sapphire tubes a good wear resistance and scratching resistance and can stay stable in relative hard condition.

2. Good wear resistance: Owing to sapphire tubes' high hardness, sapphire tubes' wear resistance is very great. Sapphire tubes can maintain structual integrity  and surface finishment after a long term use.

3. Good chemical performance: Sapphire tubes have a good chemical performance, they have a resistance to chemical corrosion, they are a good aterial against acid and corrosion.

4. High temperature resistance: Sapphire tubes's melting point  is 2053℃, their highest working temperature is 1950℃. So sapphire tubes can be applied in high temperature condotions

5. Extensive use: Sapphire tubes can be used in extensive fields, from laser systmes, optical instrements, high temperature fumaces to chemical instrument processing.
