Home >Invar 42 Bar
Hakan Nickel Alloys, a leading manufacturer and supplier located in Istanbul, Turkey, specializes in high-quality Invar 42 Bars. These bars are specifically designed for applications that demand minimal thermal expansion and outstanding dimensional stability. Known for their remarkably low coefficient of thermal expansion, Invar 42 Bars find their place in precision engineering, aerospace, and scientific equipment. Produced under rigorous quality control and adhering to international standards, Hakan Nickel Alloys guarantees that these bars deliver consistent performance, reliability, and durability, making them the go-to choice for industries where temperature fluctuations can lead to dimensional changes.
Invar 42 Bars are primarily made up of iron (about 58%) and nickel (roughly 42%), along with small amounts of carbon and other alloying elements. This specific composition gives them an incredibly low coefficient of thermal expansion (around 1.2 × 10⁻⁶ /°C), ensuring they maintain their shape across a broad temperature range. In terms of mechanical properties, Invar 42 boasts moderate tensile strength (approximately 550–700 MPa) and good ductility, paired with excellent toughness. These unique characteristics make it perfect for precision components that need to retain their shape during thermal cycling, while also providing corrosion resistance and ease of machining.
