Manganin Nickel Copper Alloy Strip For Ultra High Pressure Sensitive Material
Manganin(6J8 6J12 6J13) Copper Nickel Manganese Alloy Tape/Strip For Ultra High Pressure Sensitive Material
General Description
Manganin foil and wire is used in the manufacture of resistors, particularly ammeter shunts, because of its virtually zero temperature coeffcient 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 hydrostaticpressure sensitivity.
