Based in Hyderabad, India, Daksh Sheets and Plates is a well-known producer and supplier of premium metal goods, relied upon to provide precisely engineered materials to a range of industrial sectors. Invar 42, a special low-expansion alloy renowned for its dimensional stability over a broad temperature range, is one of our specialty products. Applications needing thermal accuracy and stability depend on Invar 42 sheets and plates, which are designed for high-performance settings. Daksh Sheets and Plates is your dependable partner for premium-grade Invar 42 products made to your exact specifications because of their dedication to craftsmanship, prompt delivery, and customer satisfaction.
Because of its low coefficient of thermal expansion (CTE), Invar 42 is a nickel-iron alloy that is made up of roughly 42% nickel and 58% iron. Under temperature fluctuations, this characteristic guarantees exceptional dimensional stability. The alloy exhibits outstanding ductility, fatigue resistance, and machinability with a tensile strength of approximately 620 MPa, yield strength of 300 MPa, and elongation of roughly 30%. Additionally, Invar 42 is very weldable, making it simple to fabricate and incorporate into intricate assemblies. Because of these qualities, it is essential for applications that call for both mechanical strength and thermal stability.
