Invar® Rod
Invar® Rod (Fe 64/Ni 36, Invar® 36), a controlled expansion iron-nickel alloy, exhibits an exceptionally low coefficient of thermal expansion (CTE), making it essential for applications requiring extreme dimensional stability. It is widely used in aerospace structural supports, interferometer frames, and satellite instruments, where temperature fluctuations could otherwise lead to misalignment. In semiconductor manufacturing, Invar® Rod ensures precision in wafer alignment and tooling, minimizing thermal distortion in high-accuracy environments. Additionally, its high strength, corrosion resistance, and machinability make it suitable for scientific instruments, cryogenic storage vessels, and metrology systems used in laboratory research and advanced engineering industries.
