Fechral. Name consonant sound of a steel blade through the air. At the same time it felt lightness and formidable force. Fechral — an alloy of metals 3, gave the title material: Fe — iron, of Cr — chrome, of Al — aluminum. Iron is the basis of alloy, it contains at least 70%. Fechral addition contains small amounts of manganese, silicon. To impart specific properties, may be nickel or other additive elements.

|H23YU5T||CrAl May 25||1.4765||92500||Kathal APM|
|H15YU5||CrAl April 14||1.4725||K91670||Alkrothal 14|
|H23YU5||CrAl May 20||1.4767||K92400||Kanthal D|
Fechral has a melting temperature: about 1,500 ° C. The electrical resistance of 1.2 — 1.3 Omxmm2 / m, and the density of only 7.2 g / cm³. Fechral is 17% lighter than nichrome, and the cost of its manufacturing cost is 6 times cheaper. Deficient in nickel alloy is replaced by a cheap aluminum and iron. When the alloy exhibits high corrosion resistance in: oxidizing carbonaceous, sulphurous environments. However, the increased fragility of the material makes it impossible to produce a very thin foil or thread. This drawback is partially offset by the introduction of the nickel, but it increases the price of the alloy.
