18-50GA Cold Rolled Ni80Cr20 / Heat Resistant Wire For Electronic Cigarettes
18-50GA Ni80Cr20 resistance heating wire for electronic cigarettes
Applications
Nichrome wire heating elements are widely used for making electric heating elements in home appliances and OCr25AL5 Electric Heating Alloy/Fecral Wire
industrial furnaces. Typical applications are electronic cigarettes,flat irons, ironing machines, water heaters, plastic moulding dies, spiral resistance heating wire
soldering irons, metal sheathed tubular elements and cartridge elements.

serious: many of our customer buy Awg 20 24 26 28 wire for e-cig.
Process:
Wire: Material preparation→melting→re-melting→forging→hot rolling→heat treatment→surface treatment→drawing(rolling)→finish heat treatment→inspection→package→warehouse
Strip:Material preparation→melting(vacuum,medium frequency)→electroslag→lathe-forging→planing→hot rolling→annealing→polish by high pressurewater→rolling→degrease→annealing→welding→rolling→edge shearing→annealing→slitting→inspection→package
when you order wire, please tell me wire material ( ocr25al5 or cr20ni80 ), please also tell me wire diameter you need, because different diameter have different price.
regular size
Wire: 0.018mm-10mm
