Resistivity of alloy manganin

Manganin is a trademarked name for an alloy of typically 84.2% copper, 12.1% manganese, and 3.7% 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 … See more In 1887 Edward Weston discovered that metals can have a negative temperature coefficient of resistance, inventing what he called his "Alloy No. 2." It was produced in Germany where it was renamed "Constantan". … See more List of named alloys See more • Isabellenhütte - 1889 Manganin See more WebManganin alloy is used for making resistors due to the following reasons: 1) Maganin has a low-temperature coefficient of resistance.
