View Product Description

Kovar Tube is a special alloy tube using the brand Kovar. Kovar is a low thermal expansion alloy composed mainly of nickel (approximately 29%), cobalt (approximately 17%) and iron (approximately 53%). Kovar Tube is widely used in many fields due to its excellent thermal expansion properties, dimensional stability and processability.

Thermal expansion properties of Kovar Tube are one of its most notable features. It has a thermal expansion coefficient close to that of materials such as glass and ceramics, making it an ideal packaging and joining material. When the temperature changes, the stress and mismatch problems between the Kovar Tube and the glass or ceramic are greatly reduced, ensuring the stability and reliability of the package.
