Kovar Sheets and Plates provide excellent thermal expansion properties, making them ideal for applications requiring good compatibility with materials such as glass and ceramics Due to low coefficient of thermal expansion they maintain stability under temperature changes. Kovar also has good mechanical strength, corrosion resistance and strong weldability, making it suitable for harsh environments. Its magnetic properties are stable, making it useful in electronics and aerospace applications, especially for hermetic sealing of components. These features make Kovar ideal for high-performance precision applications.
Kovar Sheets and Plates find extensive use in aerospace, electronics, vacuum tubes, and hermetic sealing applications. They are particularly well-suited for creating electronic package leads, glass-to-metal seals, components in sensors, and other precision instruments that require controlled thermal expansion. The alloy’s ability to maintain dimensional stability despite temperature fluctuations ensures reliable performance in high-precision and high-reliability settings. With its superior thermal expansion matching, strength, and corrosion resistance, Kovar Sheets and Plates are the go-to choice for critical industrial and scientific applications.
