Product Description


Custom-Sized Al2O3 Sapphire Glass Tube with Precision Grooves​

Product description

  Because of its excellent physical and chemical properties, sapphire pipe is widely used in various high-end industrial and technological fields. Typically made of single crystal sapphire, these tubes have extremely high hardness and corrosion resistance, and are able to withstand extreme environmental conditions such as high temperature, high pressure and corrosive chemicals. The transparency of sapphire tubes also makes them very popular in optical applications, often used in laser technology, fiber optic communications, and Windows of high-precision instruments.

  In addition, the thermal stability and electrical insulation of sapphire tubes make it an important application in the semiconductor and electronics industry, such as as an insulating or protective layer. In the medical field, due to its good biocompatibility, sapphire tubes are also used in various medical devices and endoscopic equipment. Its non-adhesion properties and chemical resistance ensure stable performance even under harsh conditions.

  In summary, the high performance and versatility of sapphire pipe make it an indispensable material choice in many fields, providing a practical and efficient solution that meets the high standards of modern industrial and technological development.
