Kovar Foil is primarily composed of iron, nickel, and cobalt, creating a material with a very low coefficient of thermal expansion. This alloy exhibits excellent dimensional stability over a wide temperature range, high tensile strength, and good toughness. Kovar Foil also demonstrates reliable machinability and formability while maintaining structural integrity under thermal cycling. Its controlled expansion properties make it ideal for bonding with glass and ceramics without causing stress fractures. These mechanical characteristics ensure that Kovar Foil performs consistently in high-precision and temperature-sensitive applications.
