Tape fechral h23yu5t - 1.4765 - kanthal A-1®
Fehralevaya tape in great demand of modern industry, where there is a huge amperage, high temperatures, aggressive environment. This broad scope of application of the best due to the composition of three components: chromium, aluminum, iron. Hence the name: Fairy — Ferrum (70−80% Fe), xp — Cr and Al — Al. Also present are limited additions of silicon (1%) and manganese (0.7%). Different mixing ratio determines the different properties of the respective brands.
Tape H15YU5 brands and different H23YU5T significant electrical resistance — up to 1.3 ohm mm2 / m and t ° melting 1450 ° C. High conversion yield makes it possible to use semi-finished minimum section. Remarkable high corrosion resistance in a vacuum, oxidizing, sulfur- and carbon-containing environments, argon, air. Specific weight — 7.2 g / cm³ can save on weight — not less than 15%. Production costs fehrali 6 times lower than the cost of nichrome.
The excessive hardness and brittleness, impeding rolling. It is not possible to roll-section of less than 0.1 mm. Very thin strip obtained is not rolling, and electrolysis. For the production of very fine yarns, this material is also not good.
Tape H15YU5 and H23YU5T used in resistors — devices for the regulation of electric power. During braking, the electric resistors are overheated. The use of such devices in fehrali justified exceptional electrical resistance unchanged at high temperatures and heat resistance, which ensures reliable operation of the circuit. Band resistors fehralevye KF series — always included in the power circuit. Another area of application — blocks ballasts resistors truck cranes. They are included in the electric circuit in order to switch the motor more smoothly occurred. These resistors adjust the speed brake motors AC and DC.
