Cr20ni80 Nickel Alloy Sheet Nickel-chromium alloy/ Nickel Chrome Wire (NCHW) for Resistor
Shanghai Tankii Alloy Material Co., Ltd. is a professional producer of NCHW1, NCHW2, FCHW1, FCHW2, CN49, CN30, CN15, CN5 in the shape of round wire, strip, sheet, rod, bar and flat wire.
NCHW-1, NCHW-2, FCHW-1, FCHW-2
The high aluminum content, in combination with the high chromium content let the scaling temperature can reach to 1425ºC (2600ºF);
Heating wires shaped by means of high speed automatic cooling machine of which the power capacity is controlled by computer, they are available as wire and ribbon.The Alloy resistance Heating Wire includes pure nickel, chromium alloy, iron-chromium aluminum alloy and copper-nickel alloy.
Fecral resistance Heating Wire is produced by melting, rolling, forging, annealing, drawing, surface treatment, resistance control
test and other methods.
Features1. High using temperature, the maximum using temperature can reach 1400C (0Cr21A16Nb, 0Cr27A17Mo2, etc.) 2. Low temperature
coefficient of resistance
3. Lower thermal expansion coefficient than the Ni-base super-alloys.
4. High electrical resistivity
5. Good corrosion resistance under high temperature, especially under the atmosphere containing sulfides
6. High surface load
7. Creep-resistant
8. Lower raw-material cost, Lower density and cheaper price compared with Nichrome wire.
9. Superior oxidation resistance at 800-1300ºC
10. Long service life
Application Area Fecral Alloy Cr15Ni60 electric resistance Heating Wire is main widely used in manufacturing industrial furnaces, civil heating equipment, various resistors and locomotive brake resistors and other heating equipment.And Cr15Ni60 electric resistance Heating Wire is also suitable for keeping the car's hot seat and steering wheel warm, refrigerator, air conditioner, USB cable heater for heating, electric blanket, towel, foot massage, electric stove, pet pillow, hot clothes, window heating, plumbing Freeze protection, electric slimming belt, pet incubator, medical care equipment.
