Manganin Wire CuMn12Ni Constantan Wire 0.09mm for Slide
Resistance
Product Description
Constantan and Manganin is a copper-nickel alloy that contains
specific minor amounts of additional elements to achieve precise
values for the temperature coefficient of resistivity. Careful
control of melting and conversion practices results in a very low
level of pinholes at ultra-thin thicknesses. The alloy is used
extensively for foil resistors and strain gauges.
