Kovar Sheets and Plates are primarily made up of iron, nickel (about 29%), and cobalt (around 17%). This carefully balanced composition results in a low and predictable coefficient of thermal expansion, which closely aligns with that of glass and ceramics. In terms of mechanical properties, Kovar boasts moderate tensile strength, good ductility, and excellent formability. It maintains its dimensional stability over a wide temperature range and offers good weldability and machinability, making it ideal for precision applications and sealing solutions.
