| Application areas | It is an ideal alloy for winding heavy-duty industrial rheostats and electric motor starter resistances. High specific resistance, together with good ductility and resistance to corrosion are all-important requirements in the category, and Constantans satisfies the most demanding specifications. It is commonly used as a thermocouple alloy, in conjunctions with copper up to 400 °C and with iron up to 800 °C. In addition, it is used in precision resistors, temperature stable potentiometer, volume control devices and strain gauges. In the resistor field, its high resistance and negligible temperature coefficient of resistance are its main attractions. | |
