Kovar Foil is primarily made up of nickel, cobalt, and iron, blended in a carefully controlled ratio to align with the thermal expansion of borosilicate glass and ceramics. This specific composition grants it remarkable dimensional stability, low thermal expansion, and impressive mechanical strength across a broad temperature range. Kovar foil also showcases good corrosion resistance and weldability, allowing it to be shaped, soldered, or brazed without losing its essential properties. Its thermal and mechanical stability guarantees reliable sealing and structural integrity in electronic components and precision devices, where thermal mismatches could lead to failures.
