We would like to introduce our 'EGNIS Series' designed for combustion furnaces, which are resistant to chlorination and oxidation. The interior of power generation boilers is exposed to high temperatures ranging from 500°C to 1000°C, creating an environment where chlorine gas is generated. The structural materials inside the furnace significantly deteriorate due to corrosion from high-temperature chlorine and oxygen produced from burned plastics. The new material developed by our company demonstrates excellent corrosion resistance in the furnace environment, greatly extending the lifespan of structural components, which can significantly reduce boiler maintenance costs. 【Features】 ■ Excellent corrosion resistance in the furnace environment ■ Dramatically improved lifespan as structural components ■ Significant reduction in boiler maintenance costs possible *For more details, please refer to the PDF document or feel free to contact us.

"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.

"IC-LTX" is a zero-expansion alloy for astronomical observation satellites. The mirror surface is constructed with a "ClearCeram-Z EX" structure, made from a super-invar IC-LTX material with an extremely low thermal expansion rate of <0±5×10^-8/K, achieving thermal dimensional stability and low-temperature resistance. The mirror surface and telescope structure are maintained at approximately 5°C to facilitate adjustments on the ground. The panels surrounding the telescope's 6A surface are temperature-controlled, maintaining the temperature during a half-orbit (50 minutes) with an accuracy of ±0.1°C. [Features] ■ All-metal structure designed for extreme low temperatures, providing stability and high feasibility of design values. ■ The mirror surface and telescope structure are maintained at approximately 5°C to facilitate adjustments on the ground. ■ Temperature-controlled panels surrounding the telescope's 6A surface maintain the temperature during a half-orbit with an accuracy of ±0.1°C. ■ The detector is cooled with a Peltier element, keeping it below 180K. ■ The high-temperature section of the Peltier is connected to a radiator via a heat pipe for heat dissipation. *For more details, please refer to the PDF document or feel free to contact us.

The "IC-EX2" is a mold for CFRP molding (autoclave). Our developed low thermal expansion cast steel can flexibly accommodate complex shapes due to the casting process. Since it overcomes the challenges of low mechanical properties, which is a weakness of cast steel, it holds great potential as a mold for precision CFRP molding with excellent mass production capabilities. 【Features】 ■ Improved strength: Increased mold lifespan ■ Cast steel: Significant cost reduction compared to machining from forged steel ■ Cryogenic treatment + annealing ■ 200℃ strength is twice that of commercial products *For more details, please refer to the PDF document or feel free to contact us.
