Product Description

Manganin is an alloy of typically 86% copper,12% manganese,and 2%nickel.

A resistance  alloy with moderate resistivity and low temperature coefficent.The resistance/temperature curve is not as flat  as the constantans nor are the corrosion resistance properties as good.

Below alloys can be suppied in the form of round wires in the range 8.0 to 0.02 mm in bare or enamelled condition,also with rayon or silk covering . The  product line includes sheets,ribbons,flat wires ,stranded wires,rods and tubes.

Manganin foil and wire is used in the manufacture of resistors,particularly ammeter shunts,because of its virtually zero temperature coefficient of resistance  value  and long term stability.Several manganin resistors served as the legal standard for the ohm.Manganin wire is also used as an electrical conductor in cryogenic systems,minimizing heat transfer between points which need electrical connections.
