1mm*8mm BMN13-2 Electric Resistance Alloy Flat Wire / Flat Strip
Manganin is a trademarked name for an alloy of typically 84% copper, 12% manganese, and 4% nickel. It was first developed by Edward Weston in 1892, improving upon his Constantan (1887).
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 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.
Manganin wire( cupro-manganese wire ) is a trademarked name for an alloy of typically 86%copper,12%manganese, and 2-5%nickel .
Manganin wire and foil is used in the manufactue of resistor,particularly ammeter shunts ,because of its cirtually zero temperature cofficient of resintance value and long terms stability.
