Relevance

Fechral ribbon is widely demanded by modern industry where there is a huge amount of current, high temperatures, aggressive environment. Such a wide range of applications is due to the successful composition of the three components: chromium, aluminum, iron. Hence the name: Fe - ferrum (70-80% Fe), Cr - Cr and Al - Al. Limited additions of silicon (1%) and manganese (0.7%) are also present. Different ratios of components determine the different properties of the respective grades.

Advantages of

Tape grades X15Yu5 and X23Yu5T have a significant electrical resistance - up to 1.3 Ohm-mm2/m and t° of melting about 1450 °C. High yield strength makes it possible to use semi-finished products of minimum cross-section. Remarkable is high corrosion resistance in vacuum, oxidizing, sulfur- and carbon-containing environments, in argon, in air. Specific weight of 7.2 g/cm3 allows to save at least 15% on weight. The production cost of fahlali is 6 times lower than that of nichrome.

Disadvantages

Over-hardness and brittleness that make the rolling process difficult. It is impossible to roll a section of less than 0.1 mm. The thinnest strip is produced not by rolling, but by electrolysis. This material is also not suitable for the production of the finest threads.

Use

Tape X15Yu5 and X23Yu5T is used in resistors - devices to regulate the force of electric current. During braking of electric trains such resistors overheat. Application of fehral in such devices is substantiated by exceptional electrical resistance, unchangeable at high temperatures and heat resistance, which ensures reliable operation of the circuit. Fechral ribbon resistors of the KF series are a must in power circuits. Another area of application is the start-up resistor units for truck cranes. They are included in the circuit of electric motors so that the motor can be switched on more smoothly. These resistors regulate the braking speed of DC and AC motors.
