Technical Characteristics of Fechrali
Alloy fechral is designed as a cheaper analog of nichrome in connection with the need to reduce the cost of production. This alloy is distinguished by high corrosion resistance, combines high t ° melting and considerable electrical resistance: up to 1.3 ohm • mm 2 / m ,. Due to the use of inexpensive aluminum instead of nickel, the cost of production is reduced by 6 times compared with nichrome.
Production and supply
Fechral wire is produced by pressing, drawing or rolling. It is wound on a coil or folded by a bay. Fechral tape is produced by the rolling or electrolysis method, after which it is rolled up by rolls.

The Achilles' heel of fehrali is fragility, making it difficult to make thin ribbons and wire from it. This disadvantage is eliminated by additives of nickel.
