Product Description

Enamelled constantan wire cooper nickel Alloy CuNi44/CuNi45/CuNi40

Product Description
These enameled resistance wires have been broadly used for standard resistors, automobile
parts, winding resistors, etc. using the insulation processing best suited for these applications, taking full advantage of the distinctive features of enamel coating.
Furthermore, we will carry out enamel coating insulation of precious metal wire such as silver and platinum wire upon order. Please make use of this production-on-order.

Application of Constantan
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.
