Ultimate Invar Alloy "IC-DX"
Zero expansion - does not undergo structural transformation up to -269°C! The Young's modulus is 1.5 times that of commercial products!
"IC-DX" is a low thermal expansion alloy based on Fe-Co-Cr. Since it does not contain Ni, which raises the Ms point, it can achieve both zero thermal expansion and low-temperature structural stability, making it suitable for use in low-temperature environments. This material is being evaluated for use as a pad material for bonding 200mm square fused quartz (aspheric mirrors). Thermal expansion at the operating temperature of 77K (liquid nitrogen) and during alignment adjustments from room temperature to 77K is important. 【Features】 ■ Zero expansion, ultra-low temperature stability, high rigidity, corrosion resistance ■ Coefficient of thermal expansion: 0 ppm/℃ ■ Lower limit temperature for low-temperature use: minus 269℃ ■ Young's modulus: 176 GPa ■ Corrosion resistance equivalent to SUS304 *For more details, please refer to the PDF document or feel free to contact us.
