Stable Resistivity Nichrome Wire NiCr6015/Cr15ni60/X15h60/Nch (R)
W2 for Electric Heating Element
Nickel Chromium Alloy Introduction:
Nickel Chromium alloy has high resistivity, good anti-oxidation
properties, high temperature strength, very good form stability and
weld ability. It is widely used in electrical heating element
material, resistor, industrial furnaces, etc.
Ni60Cr15 nickel chromium alloy wire is an ideal material, it has
good ductility,workability and weldability under high temperature
and seismic strength.
Nickel-chromium alloy with high and stable resistance, corrosion
resistance, surface oxidation resistance, excellent coil-forming
ability.
We also produce other kind of nichrome resistance wire, such as
NiCr 70/30,NiCr 60/15,NiCr 60/23,NiCr 37/18, NiCr 35/20, NiCr
35/20, NiCr 25/20,Karma
Grade: Ni80Cr20 ,also called Nikrothal 8,MWS-650,NiCrA,Tophet A,HAI-NiCr
80,Chromel A,Alloy A,N8,Resistohm 80, Stablohm 650,Nichorme
V,Nikrothal 80 etc.
Application of Different Grades:
Cr15Ni60:in braking resistors,industrial furnaces,hot plates,
grills, toaster ovens and storage heaters. For suspended coils in
air heaters in clothes dryers, fan heaters, hand dryers.
Cr20Ni80:in braking resistors,industrial furnaces,flat irons,
ironing machines, water heaters, plastic moulding dies, soldering
irons, metal sheathed tubular elements and cartridge elements.
Cr30Ni70:in industrial furnaces. well suited for reducing
atmospheres, as it is not subject to 'green rot'.
Cr20Ni35:in braking resistors,industrial furnaces.In night-storage
heaters, convection heaters, heavy duty rheostats and fan heaters.
For heating cables and rope heaters in defrosting and de-icing
elements, electric blankets and pads, car seats, baseboard heaters
and floorheater.
Cr20Ni30:in solid hot plates, open coil heaters in HVAC systems,
night-storage heaters, convection heaters, heavy duty rheostats and
fan heaters.For heating cables and rope heaters in defrosting and
de-icing elements, electric blankets and pads, car seats, baseboard
heaters, floor heaters and resistors.
