Nestled in the industrial heart of Amman, Jordan, Nizar Sheetsandplates stands as a dedicated manufacturer and supplier for specialized material needs. We take particular pride in producing high-quality Kovar Foil, a material engineered for precision and reliability. Understanding the critical nature of modern electronics and aerospace components, we focus on delivering foil that meets the exacting standards our clients depend on for their most innovative projects, providing a trusted local source for this essential advanced alloy.
Kovar Foil possesses a unique chemical composition, primarily an iron-nickel-cobalt alloy, which is precisely controlled to give it a special talent. Its most valuable mechanical property is a thermal expansion rate that closely matches that of borosilicate glass and certain ceramics. This means it expands and contracts at nearly the same rate when heated or cooled, which prevents stress and cracking. This characteristic, combined with its good strength and ductility, makes it an incredibly dependable material in demanding environments.

Kovar foil is a high-performance alloy made primarily of iron, nickel and cobalt, which offers exceptional benefits in specialized applications. Its low thermal expansion makes it ideal for glass coatings on metals in electronics, ensuring stability under temperature changes Coatings are also highly resistant to thermal cycling, providing durability in internal environments is strong. Its excellent mechanical properties and ease of manufacture make it suitable for precisely complex designs, while the ability to maintain excellent performance at high temperatures ensures reliable performance at aerospace, electronics and pharmaceutical industries.
The primary use of Kovar Foil is creating a perfect, hermetic seal between metal and glass or ceramic components, which is absolutely vital in industries like aerospace and telecommunications. You’ll find it in the protective packages of sensitive semiconductors, integrated circuits, and transistors. It’s also essential inside lasers, x-ray tubes, and various high-power lighting systems where a reliable, airtight seal must withstand significant temperature fluctuations without failing. Essentially, wherever a durable and precise connection is needed, Kovar Foil is the unsung hero ensuring everything holds together perfectly.
