Hakan Nickel Alloys, a prominent manufacturer and supplier located in Istanbul, Turkey, specializes in high-quality Invar 36 Bars. These bars are specifically designed for applications that require minimal thermal expansion and precise dimensional stability. Known for their remarkable ability to retain their shape even with temperature changes, they find extensive use in aerospace, scientific instrumentation, and precision engineering. Produced under strict quality controls and adhering to international standards, Hakan Nickel Alloys guarantees that their Invar 36 Bars provide consistent performance, durability, and reliability, making them the go-to choice for critical applications where controlling thermal expansion is essential.
Invar 36 Bars are primarily made up of iron (about 64%) and nickel (around 36%), along with small amounts of carbon and other alloying elements. This unique composition results in an exceptionally low coefficient of thermal expansion (approximately 1.2 × 10⁻⁶ /°C), ensuring that they maintain their dimensions across a wide temperature range. In terms of mechanical properties, Invar 36 offers moderate tensile strength (roughly 500–700 MPa), good ductility, and excellent toughness. Its low thermal expansion, combined with corrosion resistance and ease of machining, makes it perfect for precision components and structural applications that need to withstand thermal stress.
