Kovar Sheets Foil is primarily made up of iron, nickel, and cobalt, typically consisting of about 54% Fe, 29% Ni, and 17% Co. This carefully balanced alloy composition allows for a thermal expansion coefficient that closely aligns with that of glass and ceramic materials. On the mechanical side, Kovar foil boasts good ductility, impressive tensile strength, and excellent dimensional stability, even when subjected to temperature variations. It retains its structural integrity during thermal cycling and delivers reliable performance in environments that require hermetic sealing. Its formability and predictable thermal behavior make Kovar foil perfect for delicate, high-precision components.
