Enameled Manganin Wire/Low Resistance Alloy Wire
Enameled Manganin Wire/Low Resistance Alloy Wire
Product Description
Manganin is an alloy of typically 86% copper, 12 % manganese, and 2% nickel.
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 Manganin
Manganin foil and wire is used in the manufacture of resistor, Particularly ammeter shunt, because of its virtually zero temperature coefficient of resistance value and long term stability.
