Hakan Nickel Alloys, a prominent manufacturer and supplier located in Istanbul, Turkey, specializes in high-quality Kovar Sheets and Plates. These products are crafted for precision applications that demand exceptional thermal expansion control and mechanical stability. Renowned for their unique compatibility with glass and ceramic materials, Kovar Sheets and Plates find extensive use in the electronics, aerospace, and scientific sectors. Produced under rigorous quality standards, Hakan Nickel Alloys guarantees that their Kovar Sheets and Plates offer consistent dimensional stability, reliable performance, and outstanding durability, making them perfect for applications where precise thermal and mechanical properties are crucial.
Kovar Sheets and Plates are primarily made up of iron (about 54%), nickel (29%), and cobalt (17%), along with small amounts of other elements that enhance stability and machinability. This specific composition results in a controlled coefficient of thermal expansion (~5 × 10⁻⁶ /°C) that closely aligns with borosilicate glass and ceramics. On the mechanical side, Kovar boasts moderate tensile strength (around 500–700 MPa), excellent toughness, and good ductility. Its ability to maintain dimensional stability under temperature changes, along with its ease of fabrication and corrosion resistance, makes it an ideal choice for precision components in high-reliability applications.
