A reputable manufacturer and supplier in Chennai, India, Kunj Sheets and Plates specialises in offering premium Invar Sheets and Plates for a range of industrial applications. Kunj has a solid reputation for providing industries that need materials with low thermal expansion with high-quality, precisely engineered materials. Because of their remarkable dimensional stability, particularly in a range of temperature conditions, Invar Sheets and Plates are perfect for precision instruments and aerospace parts. In the defence, electronics, and engineering sectors, Kunj guarantees that every product satisfies exacting international standards and customer-specific requirements by committing to quality, competitive pricing, and on-time delivery.
Invar Sheets and Plates have a very low coefficient of thermal expansion because their main constituents are 36% nickel and 64% iron. Excellent dimensional stability over a broad temperature range is made possible by this composition. Invar is perfect for cold working and forming because of its high ductility, yield strength of roughly 300 MPa, and tensile strength of roughly 500–700 MPa. Reliable performance in precision environments is ensured by the alloy’s moderate corrosion resistance and good magnetic properties. It is essential for high-accuracy applications because it preserves structural integrity and resists distortion under heat stress.
