Description

ASTM F75 (UNS R30075) cobalt alloy Printdur® CoCrF75 can be used in two different application areas:


  • high-temperature applications
  • medical engineering

  • Printdur® CoCrF75 has an excellent resistance to thermal shock in the heat-treated condition and is resistant to oxidizing and reducing atmospheres up to approx. 1150 °C. Due to these properties, Printdur® CoCrF75 is preferred for high temperature applications. In addition to its excellent thermal shock resistance and the high resistance to oxidizing and reducing atmospheres, Printdur® CoCrF75 with other properties in medical engineering:


  • Very good biocompatibility
  • Very high corrosion resistance
  • Related Standards
