Product Details

Kovar Strip is a special alloy strip using the brand Kovar, which has excellent performance and a wide range of applications.

The brand name of Kovar Strip is Kovar, which is an alloy composed of elements such as nickel, cobalt and iron. This alloy is known for its low thermal expansion properties, with a thermal expansion coefficient close to that of materials such as glass and ceramics, making it ideal for packaging and connection applications. Kovar Strip also has excellent dimensional stability and can maintain small dimensional changes under temperature changes, thereby reducing stress and mismatch issues during the packaging process. In addition, Kovar Strip also has good processability and can be made into strips of different specifications and shapes through hot or cold processing to meet various application needs.
