Kovar Sheets Foil is a specialized alloy known for its unique composition of iron, nickel, and cobalt. This specific blend gives it a thermal expansion rate that closely matches certain types of glass and ceramics, which is its key characteristic. Mechanically, it offers good strength and excellent ductility, making it relatively easy to fabricate into precise shapes while maintaining its crucial dimensional stability across a wide temperature range, which is essential for creating reliable, long-lasting seals.

The primary use of Kovar Sheets Foil is in creating hermetic seals in electronic and semiconductor packaging. You’ll find it in everything from power transistors and integrated circuits to microwave tubes and laser diodes, where it forms a perfect bridge between glass or ceramic insulators and metal components. Its reliability also makes it invaluable in aerospace applications, certain lighting systems, and any other technology where a stable, leak-proof seal must withstand significant thermal cycling without failing.
