QuNi36 - Bobbin
Product number:
Qu3602-200-MA125
Product information "QuNi36 - Bobbin"
QuNi36 is a binary iron-nickel-alloy with an extremely low coefficient of thermal
expansion. The content of carbon and manganese by simultaneous absence of other
impurities has a great influence on this characteristic. By cold forming the material, the
thermal expansion can be lowered. A step by step thermo treatment of the material
generates a man-made aging, by which the coefficient of thermal expansion can be
stabilized within a specific temperature range. The basic material 1.3912 is distinguished
by an extremely low coefficient of expansion between -250°C and 200°C and at the same
time, good ductility and toughness.
Recommendation for
Tester and check instruments (e.g. thermostat); constructions for the production, storage
and transport of liquide gases; connectors for bolted assemblies for metals with different
characteristics; forms of the production of CFK-parts (aircraft industry); frames,
attachments and boxes for controll units at the construction of satelites
