Fecral 0cr23al5 Alloy High Temp 5kw Electric Heating Element Resistance Coil Wire

Fecral 0cr23al5 Alloy High Temp 5kw Electric Heating Element Resistance Coil Wire

Fecral  heating wire The high aluminum content, in combination with the high chromium content let the scaling temperature can reach to 1425ºC (2600ºF);

FeCrAl wire is 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.

Product forms and size range 

Round wire 

0.010-12 mm (0.00039-0.472 inch) other sizes are available on request.

Ribbon (flat wire) 

Thickness: 0.023-0.8 mm (0.0009-0.031 inch) 

Width: 0.038-4 mm (0.0015-0.157 inch) 

Width/thickness ratio max 60, depending on alloy and tolerance 

Other sizes are available on request.

Resistance electric heating wire has strong antioxidant properties, but a variety of gases in furnaces such as air, carbon, sulfur, hydrogen and nitrogen atmosphere, still have a certain impact on it. 

Although these heating wires all have had antioxidant treatment, the transportation, winding, installation and other process will cause damage to a certain extent and reduce its service life.

In order to extend the service life, customers need to do pre oxidation treatment before using.This methos is to heat alloy elements with have installed completely in the dry air to the temperature  (lower 100-200C than its maximum using temperature), heat preservation for 5 to 10 hours, then cooling slowly with furnace.

FeCrAl heating wire Features and advantages

1. 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

FeCrAl heating wire Application

Our products (FeCrAl) high resistance electric heating wire materials are salable and widely used for making heating equipment like industrial furnace, civil heating appliance, various electrical resistors and locomotive braking resistor, infrared equipment, liquefied gas infrared heat-resisting net, different kinds of igniting and radiating electrodes and voltage-regulating resistors for motors and so on in Metallurgical machinery, medical, chemical, ceramics, electronics, electrical appliance, glass and other civil or industrial fields.
