Vintage Western Germany Made during the 80's PRECISION RESISTOR WIRE MANGANIN (enamelled) BRAND NEW You bid for the following: 1 spool with the following parameters: Diameter of the thread - 0.04 mm (equals to 45.9644193649687 gauge AWG gauge ) / Resistance - 350.9 Ohm/m / Net weight - 204.9 grams Original datasheet : http://www.isabellenhuette.de/uploads/media/Technical_Information.pdf The precision resistance alloy MANGANIN®, developed by Isabellenhutte, 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. Notes on Treatment MANGANIN® can be worked easily. Though the alloy can be soldered, it develops in air a thin oxide film; this must be removed before working. With an appropriate flux MANGANIN® is also suitable for dip-tinning. Furthermore, MANGANIN® can be brazed and welded. Resistors made of MANGANIN® must be aged in order to remove mechanical stress. For further details see Technical Information. Quote from Wikipedia.org Manganin is a trademarked name for an alloy of copper, manganese, and nickel. Typically, the alloy contains 12% manganese and 2% nickel, with 86% copper. Manganin foil and wire is used in the manufacture of resistors because of its superior temperature coefficient and long term stability. Several Magnanin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. Manganin is also used in gauges for studies of high-pressure shock waves (such as those generated from the detonation of explosives) because it has low strain sensitivity but high hydrostatic pressure sensitivity.
