Resistance Alloy - MANGANIN® - Isabellenhutte USA
Swansea, MA, United States
Resistance Alloy MANGANIN®
The precision resistance alloy MANGANIN®, developed by Isabellenhütte, is especially characterized by low temperature coefficient between +20 and +50 °C with a parabolic shape of the R(T) curve, high long-term stability of electrical resistance, extremely low thermal EMF versus copper and good working properties. Due to these features MANGANIN® is the standard material for precision, standard and shunt resistors. Manganin® is the basis for the production of ISA-PLAN® and ISA-WELD® components. The maximum working temperature in air is +140 °C. However, higher thermal loads in a non-oxidizing atmosphere are possible. When used for precision resistors with the highest requirements, the resistors should be carefully stabilised and the application temperature should not exceed +60 °C. Exceeding the maximum working temperature in air may result in a resistance drift generated by oxidizing processes. Thus, the long-term stability can be affected negatively. As a result, the resistivity as well as the temperature coefficient of the electric resistance may slightly change. It is also used as low cost replacement material for silver solder for hard metal mounting. Form of Delivery Manganin® is supplied in the form of round wires in the range 0.02 to 8.00 mm ø in bare or enameled condition, also with rayon or silk covering. The product line includes sheets, ribbons, flat wires, stranded wires and rods.
