Description
Solid Soft Strain Foil Copper Nickel Alloy Wire Size 0.01mm * 100mm

    Copper Nickel Alloy Foil  (Constantan) Size 0.005mm * 100mm Use For Strain Foil

 

2. Product Description

    Constantan 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.
