Product Details

Kovar Bar is a special alloy bar using the grade Kovar. It is composed of elements such as nickel, cobalt and iron and is a low thermal expansion alloy. Kovar Bar is widely used in industrial fields due to its excellent thermal expansion properties and dimensional stability.

One of the distinguishing features of Kovar Bar is its matched coefficient of thermal expansion to the glass material. This makes it an ideal packaging material and is widely used in the electronic packaging industry. Since the thermal expansion performance of Kovar Bar is very close to that of glass, the stress and mismatch problems between it and the glass are greatly reduced when the temperature changes, ensuring the stability and reliability of the package.
