Enameled Karma Wire Copper Based Alloys Stable Resistance For Industry
Enameled Karma Wire Copper Based Alloys Stable Resistance For Industry
Enameled Alloy Wire(Karma)
Common Name:(enameled Resistor wire,enameled heating wire,enameled wound wire)
Product Description
These enameled resistance wires have been broadly used for standard resistors, High /Low Voltage Resistor 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.
