Product Description

Description
Manganin is a trade marked name for an alloy of typically 86% copper,12% manganese,and 2% nickel.
Manganin foil andwire is used in the manufacture of resistors,particularly ammeter shunts,because of its virtually zero temperature coefficients of resistance value and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990.Manganin wire is also used as an electrical conductor in cryogenic systems,minimizing heat transfer between points which need electrical connections.
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.
