Enameled Copper Nickel Wire CuNi44 for Seat Heating with 240℃ High Temperature and Corrosion Resistance

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.

Type of bare Alloy wire
The alloy we can do enamelled are Copper-nickel alloy wire,Constantan wire,Manganin wire. Kama Wire,NiCr Alloy wire,FeCrAl Alloy wire etc alloy wire

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.
