Properties and Application Notes
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.
Form of Delivery
ZERANIN® 30 is supplied in the form of round wires in the range of 8 to 0.02 mm Ø in bare or enamelled condition. Special versions can be supplied as well as flat wires, stranded wires and tubes.
Notes on Treatment
ZERANIN® 30 can be worked very easily. The alloy can be soft soldered; in air however, it develops a thin oxide film which must be removed before working. With an appropriate flux ZERANIN® 30 is also suitable for dip-tinning. ZERANIN® 30 can also be brazed and welded.
