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
