4J32 alloy wire is a precision iron-nickel-cobalt alloy with a controlled coefficient of thermal expansion. It offers excellent dimensional stability, good mechanical strength, and outstanding workability, making it an ideal material for applications requiring reliable glass-to-metal sealing and thermal expansion matching.
The thermal expansion characteristics of 4J32 are well matched with specific hard glasses and ceramic materials, ensuring excellent sealing performance and long-term reliability under varying temperature conditions. It is widely used in electronic components, vacuum devices, semiconductor packaging, relays, hermetic connectors, precision instruments, aerospace equipment, and other high-reliability applications.
Our 4J32 alloy wire is manufactured under strict quality control to ensure consistent chemical composition, precise dimensional tolerance, excellent surface finish, and stable physical properties. We can supply various wire diameters and tempers (annealed, semi-hard, and hard) according to customer requirements, with customized specifications available for different industrial applications.
