Copper Alloy
Copper Nickel Resistance Alloy principally destined for the manufacturing of low temperatures electric resistances so as heating cables, shunts, resistances for automobile, they have a maximum operating temperature of 752°F. The most known, Constantan presents the advantage of a very low temperature coefficient. Their advantages are the following: very good resistance to corrosion, Very good malleability and very good solderability.
Manganin is a trademarked name for an alloy of typically 86% copper, 12% manganese, and 2% nickel. This resistance alloy has moderate resistivity and low temperature coefficient. The resistance/temperature curve is not as flat as the constantans nor are the corrosion resistance properties as good. It is used in the manufacture of resistors, particularly ammeter shunts.
