ZERANIN 30

ZERANIN® 30 is well known for its low temperature coefficient
between +20 and +60 °C with a very flat parabolic shape of the
R(T)-curve, high long-term stability of the electrical resistance,
low thermal EMF versus copper and good workability. In addition,
the very low temperature coefficient applies to a relatively wide
temperature range. This alloy is mainly used for precision resistors.
The maximum working temperature in air is +140 °C. However, higher
thermal loads in a non-oxidizing atmosphere are possible. Exceeding
the maximum working temperature in air may result in a resistance
drift generated by oxidizing processes. Thus, the long-term stability
could be affected negatively. As a result, the resistivity as well as
the temperature coefficient of the electric resistance may change
slightly.
