Fehral wire

Fehral wire 0Cr25Al5 is one kind of normal alloy material.

FeCrAl alloy has the characteristics of high specific resistance, high resistance coefficient, high working temperature, good antioxidation and anticorrosion resistance at high temperature.

Widely used in industrial furnaces, household appliances, industrial furnaces, metallurgy, mechanical engineering, aviation, automotive, military and other industries that produce heating elements and resistance elements.

Fechral is a precision iron-based alloy consisting of the following elements:

• Cr (12-27%);
• Al (3.5-5.5%);
• Si (1 %);
• Mn (0.7%);
• other is Fe.

It is a hard, brittle alloy that is difficult to machine, has a high specific electrical resistance of 1.2-1.3 μOhm·m (1.2-1.3 Ohm·mm²/m). Density 7100-7300 kg/m3, melting point about 1450 °C. The highest operating temperature is 1400 °C (for Kanthal A1[1]).

Resistant to oxidation in air at high temperature.

It is used for the production of heating elements of powerful electronic heating devices of industrial and technological furnaces, starting and braking resistors of electric locomotives, rolling stock, in electronic cigarettes as a heating element.

After its first (after manufacturing) heating to 350-400 °С, it becomes brittle due to recrystallization. After heating, a wire with a diameter of 0.5-1 mm breaks easily, forming an uneven fracture.

Available in the form of wire, rods, tapes, plates.

 

We provide wire (fehral) of the following diameters

 

Size range

• Wire: 0.01-10 mm.
• Tapes: 0.05 * 0.2 - 2.0 * 6.0 mm.
• Strip: 0.05 * 5.0-5.0 * 250 mm.
