Bilal Nickel Alloys, located in Safat, Kuwait, stands out as a top manufacturer and supplier of Kovar Foil, celebrated for its remarkable dimensional stability and thermal expansion compatibility with glass and ceramics. This nickel-cobalt-iron alloy is specifically designed to endure high-temperature conditions while keeping its structural integrity intact. Crafted to exact specifications, it delivers dependable performance across electronic, aerospace, and industrial sectors. With its unique blend of strength, corrosion resistance, and thermal matching qualities, Kovar Foil from Bilal Nickel Alloys guarantees exceptional quality, durability, and consistency, making it a go-to choice for sealing, bonding, and electronic assembly tasks.
Kovar Foil is primarily made up of 29% nickel, 17% cobalt, and the rest iron, with a few trace elements added to enhance its performance. This particular blend results in low thermal expansion that closely aligns with borosilicate glass, helping to reduce thermal stress. On the mechanical side, Kovar Foil showcases impressive tensile strength, excellent fatigue resistance, and good ductility. It maintains its dimensional stability across a broad temperature range and is resistant to oxidation and corrosion. This combination of mechanical strength and thermal compatibility makes it perfect for precision engineering applications, especially in settings that require reliable performance during thermal cycling.
