Yunus Sheets and Plates are a Turkey-based specialized manufacturer and supplier that provides high-quality Invar sheets and plates with an extremely low coefficient of thermal expansion. Manufactured using accurate alloying and heat treatment methods, our Invar materials conform to international standards and are extensively utilized in applications where dimensional stability during temperature variations is essential. Yunus Sheets and Plates caters to aerospace, precision instruments, and electronics industries, among others, with dependable steel solutions created for high-performance applications requiring minimal thermal deformation.
Invar plates and sheets are nickel-iron alloys that have about 36% nickel and 64% iron content, the reason why they have their characteristic low expansion values. The chemical make-up provides them with a very low value of the thermal expansion coefficient of about 1.2 × 10⁻⁶ /°C, much lower than most metals. Invar has good mechanical strength, very good corrosion resistance, and weldability. It has dimensional stability across a broad temperature range, for which it finds application in precision components and assemblies where thermal expansion can compromise accuracy or function.
