H23YU5T - 1.4765 - kanthal A-1® fehralevaya wire

Relevance

Fechral alloy is aluminum, chromium and iron, which is alloyed with manganese and silicon. In some cases, the wire wire to improve ductility alloyed with nickel. Wire fehralevaya — an essential component in the manufacture of thermocouples household appliances and industrial furnaces. This wire is best used in hair dryers, fan heaters, convection heaters. Fechral is used in the manufacture of resistors, resistance units, resistors — almost in the same areas as Nichrome, and due to the lack of nickel wire fehal lot cheaper, because more affordable for the buyer. This wire consists of the following elements: Cr (12−15%); Al (3,5−5,5%); Si (1%); Mn (about 0.7%); residue — Fe. It is hard, but not very ductile alloy that responds poorly to treatment. Wire fehralevaya has a high electrical resistivity. The density is 7.1 — 7.3 g / cm³, the melting point of about 1450 ° C. The maximum operating temperature up to 1400 ° C (for Kanthal). Wire Manufacturing normalized GOST 12 766.1−90. The larger its diameter, the higher the maximum operating temperature of the heater.

Classification

If the labeling is present the letter H — wire is used for the heating elements. The letter C makiuetsya wire resistance elements. Designation TEN stands for tubular electric heaters. The wire has a 0.1 mm Ø. Its price is much lower than that of counterparts, and consumer properties not worse. The relative cheapness fehrali due to the use of aluminum in the manufacture, rather than nickel, which is much more expensive. Price of products depends on the thickness: the thinner the wire — the higher the cost. The fragility of the material does not allow to use «cold» processing methods, so we have to use for the production of more energy-intensive and expensive technology. Use hot drawing, rolling, pressing. Finished wire is supplied on coils or bays.

dignity

Fehralevaya wire combines two remarkable qualities: large resistivity up to 1.3 ohm-mm ² / M and t ° Melting about 1500 ° C. Wire practically does not lose resistance with increasing temperature, which allows to use it in the production of high-temperature heating devices and resistance elements. Note also the excellent corrosion resistance in vacuo, air, argon, sulfur-containing, carbon containing, and oxidizing environment. Fechral lighter than comparable materials, specific weight = 7.2 g / cm³, can withstand severe mechanical loads without deformation. High yield strength allows the use of a thin wire diameter. Worth fechral wire about 6 times cheaper nichrome, which is a significant advantage in the marketplace. If no significant fragility, which greatly complicates the manufacture, fechral would be the ideal material. Additives to reduce the fragility of its nickel. However, this increases the cost of the final product. Fehrali price several times lower than the cost of nichrome — this has already been mentioned. The reason is simple: the aluminum material is cheaper as compared to the expensive nickel. Along with this fehrali melting temperature — above. It comes in the form of 2 half-finished: wire and tape.

Production

The wire is made by drawing, rolling or pressing. Then it is wound on a spool or winding down the bay. The tape is rolling or electrolysis. Then fold rolls. The cost of production is inversely proportional to the cross section. This alloy is very fragile. Therefore, the production of thin wires connected with the involvement of more expensive technologies. From this the final product price increases more than two times.

Using

Fehralevaya wire is widely used to convert electricity into heat, indispensable in resistance units, starting resistors are resistant to vibration, compact, relatively small weight. Another important area — blocks ballasts resistors cranes, which are included in the circuit of electric motors for a smooth start. They regulate the speed of electric motors Ramp both DC and AC. Also fehralevaya wire is used for:

· Thermocouples industrial kilns, elektrosushilok heating parts;

· Household electric heaters;

· Industrial water heaters.

Fehralevaya wire is used in the production of nepretsizionnyh (no special requirements for accuracy) resistor. This is due to the economic side, because price fehrali below.
