VDM® Alloy 36 (1.3912/K93600)

VDM® Alloy 36 is an austenitic binary iron-nickel alloy with a particularly low coefficient of expansion. Control of carbon and manganese contents as well as impurities is important.

Characteristics of VDM® Alloy 36

VDM® Alloy 36 (1.3912/K93600) is ferromagnetic at temperatures below the Curie temperature and non-magnetic at temperatures above. Cold deformation reduces the thermal expansion. A 3-step ageing treatment stabilizes the coefficient of expansion within a selected temperature range.

VDM® Alloy 36 is characterized by:

  • extremely low coefficient of thermal expansion between -250 and +200°C (-418 and 392°F)
  • good ductility and toughness
  • good fatigue and mechanical properties at cryogenic temperature

Applications of VDM® Alloy 36

Typical applications are:

  • Production, storage and transportation of liquefied gases
  • Equipment to indicate and control temperatures below 200°C (392°F), i.e., thermostats
  • Bushings for screw or bolt connections between different metals
  • Bimetallic components and thermostat metals, where VDM® Alloy 36 constitutes the passive component
  • Diaphragm frames
  • Molds for the production of carbon fiber reinforced plastic (CFRP) components
  • Frames for electronic control units for satellites and space crafts at temperatures down to -200°C (-328°F)
  • Mountings for electromagnetic lens systems in laser control devices
  • Clock pendulums
  • Components in automotive applications
