Enameled Nichrome /Constantan /Copper / Lizt / Color Wire / Silver /Twist Wire
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.

nicr8020 alloy heating wire
1.About Nichrome wire
Nichrome alloy includes pure nickel, NiCr alloy, Fe-Cr-Al alloy and copper nickel alloy.
Nickel chrome alloys: Ni80Cr20, Ni70Cr30, Ni60Cr15, Ni35Cr20, Ni30Cr20, Cr25Ni20, pure nickel Ni200 and Ni201
2.Main Advantage and Application
1. Nickel-chromium, nickel-chromium alloy with high and stable resistance, corrosion resistance, surface oxidation resistance is good, a better under high temperature and seismic strength, good ductility, good workability and weldability.
2.Our Products widely apply to chemical industry, metallurgy mechanism, glass industry, ceramic industry, home appliance area and so on.
