Formula: Fe64/Ni36
Form: Rod
Material: Invar®
Commodity: Alloys
Our Invar® Rods come in an extensive choice of 161 variations. Made from a nickel-iron alloy, they exhibit a low coefficient of thermal expansion and high strength at cryogenic temperatures, making them ideal for precision instruments and other applications requiring dimensional stability with temperature changes. Invar rods are commonly used in scientific measurement devices, aerospace components and optics mounting, where maintaining precise dimensions is critical.
