Defination of Manganin

Manganin is a Copper-Manganese-Nickel  Resistance  alloy;  it combines  all the  properties  required of  a precision electrical resistance alloy such as high resistivity, low temperature coefficient of resistance, very low thermal effect against copper and good performance of electrical resistance over long periods of time.

Alloy Available of Manganin

a) Wire φ8.00~0.02

b) Ribbon t=2.90~0.05 w=40~0.4

c) Plate (Standard) 1.0t×100w×800L

d) Foil t=0.40~0.02 w=120~5

Chemical composition of Manganin

86% copper, 12% manganese, and 2% nickel

Applications of Manganin:

a) It is used for making wire wound precision resistance

b) Resistance boxes

c) Shunts for electrical measuring instruments

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 resistance alloy sizes:

a) Wire       φ8.00~0.02

b) Ribbon  t=2.90~0.05 w=40~0.4

c) Plate      1.0t×100w×800L

d) Foil         t=0.40~0.02 w=120~5
