Relevance

Resistant — precision magnetic alloy based on iron, chromium and aluminium is highly resistant to corrosion at elevated up to 1400 °C temperatures, high-temperature strength and high electrical resistance capable of generating significant thermal power. This leads to the use of fehrali as heating elements for industrial and laboratory resistance furnaces.

Heat treatment

Feralia tape can be soft and hard. When the thickness is more than 0.2 mm it is pre-annealing with the aim of improving the ductility and decreasing the hardness of the products. Thinner tape is supplied in a solid state.

Standardization

The dependence of the electrical resistance of the material to the temperature and parameters of the cross-section is installed GOST 12766 2−90. The permitted deviation of the values of the resistance tape is available in regular quality (1) high quality (PC). Allowable deviation of electrical resistance up to 1 meter of tape from the nominal shall not exceed ± 5% for tapes of higher quality, and ± 7% for ribbon normal quality. In this variation of electrical resistance material within a coil (coil mandrels) must not exceed 4%.
