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 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.
