Xuan Nickel Alloys, a reputable manufacturer and supplier based in Da Nang, Vietnam, offers top-notch Invar Bars that are highly regarded for their exceptional thermal and mechanical properties. Crafted with meticulous attention to international standards, these bars boast an incredibly low coefficient of thermal expansion, making them essential for applications that require dimensional stability even with temperature changes. Available in a variety of sizes, grades, and finishes, Invar Bars from Xuan Nickel Alloys cater to industries like aerospace, electronics, cryogenics, and scientific instrumentation, providing reliability, precision, and durability for both specialized and industrial applications.
These Invar Bars are primarily made up of Nickel (about 36%) and Iron, with small amounts of other elements added based on specific requirements. This carefully calibrated composition leads to a remarkably low thermal expansion rate while still ensuring good toughness and machinability. Invar Bars also demonstrate decent tensile strength, ductility, and hardness, allowing them to be shaped into precise components without sacrificing mechanical stability. Their ability to maintain dimensional accuracy under both cryogenic and moderate heat conditions makes them highly effective in critical engineering applications.
