Ultra-High Temperature Stable

ArCarb-UHT focuses on thermally stable components. Along with ultra-high temperature resistance, ArCarb-UHT also offers tailored thermal conductivity based on the system requirements. ArCarb-UHT components enhance the system by pushing the thermal boundaries and achieving the optimum efficiency. ArCarb is 3 times lighter than superalloys and can withstand temperatures higher than superalloys (non-oxidising environment). Thus, making it an attractive prospect in ultra-high temperature domain.

  • Maximum temperature:
    • Oxidising environment is 450⁰C (long-term exposure)
    • Non-oxidising environment is >2000⁰C (long-term exposure)
  • The thermal conductivity can be tailored (17-150 W/mK)based on component requirements
  • Lightweight structures due to a density of 1.9 g/cm3 allows ease of handling, transfer of hot components and reduces overall weight of the system

Application Domain

  • Charging structures for metal thermal treatment
  • Handling device for discharging metal from hardening furnaces
  • Reusable rocket nozzle
  • Thermal Protection Systems
  • Hot gas liners
