0.01 - 10mm Enamelled Wire Copper Nichrome Heater Wire CuNi44
Constantan Red Black White Green
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.
