VDM® Alloy 36 is a binary iron-nickel alloy with a particularly low heat expansion coefficient, whereby the levels of carbon and manganese as well as freedom of impurities are significant. Cold forming also reduces the heat expansion.
Artificial aging with gradual heat treatment stabilizes the expansion coefficients in a selected temperature range.
VDM® Alloy 36 is characterized by:
an extremely low expansion coefficient between -250 °C (-418 °F) and +200 °C (392 °F)
good ductility and toughness.
Applications
VDM® Alloy 36 was developed for applications requiring the lowest possible heat expansion.
Typical applications are:
Manufacturing, storage and transport of liquefied gases
Components for OLED screens
Measuring and control devices for temperatures below 200 °C (392 °F), e.g. for thermostats
Bushings for screw or rivet joints between various metals
Bi-metal components and thermostatic bi-metals, where VDM® Alloy 36 is the passive component
Forms for the production of carbon-fiber reinforced plastic (CFP), especially for the aerospace industry
Frameworks for electronic control units in satellites and space travel down to -200 °C (-328 °F)
Support elements for electro-magnetic lenses in laser control units
Pendulum
Components for the automotive industry
