Description
About Manganin®
From Wikipedia: Resistance alloy with moderate resistivity and low temperature coefficent. The resistance/temperature curve is not as flat as the constantans nor are the corrosion resistance properties as good. Manganin is a trademarked name for an alloy of copper, manganese, and nickel. Typically, the alloy contains 12% manganese and 2% nickel, with 86% copper. It was first developed by Edward Weston. Manganin foil and wire is used in the manufacture of resistors because of its superior temperature coefficient and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. 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.
