1.The picture of  Iron-chrome-aluminium heat resistant electric wire 0Cr21Al6

  Iron-chrome-aluminium heat resistant electric wire 0Cr21Al6    is characterized by excellent oxidation resistance and very good form stability resulting in 

 long element life. They are typically used in electrical heating elements in industrial furnaces and home 

 appliances. FeCrAl alloys have higher service temperature than NiCr alloys,but lower stability and flexibility.

2. Characteristics:

1) The highest working temperature up to 1250  degree.

2) Longer working life,and better technical properties

3) Higher surface load.

4) Higher  resistivity.

5) Lower density.

6) Free from oxide debris

3. Applications

Iron-chrome-aluminium heat resistant electric wire 0Cr21Al6 is widely used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
