Resistance resistant wire

Where to learn about the parameters of the electrical resistance fehrloi wire. On the website of the supplier KMZ you will find the necessary information on this issue. Buy fehrali wire in a wide range of cross section and thickness the selection of KMZ. Are economically advantageous prices from manufacturers. Guaranteed product delivery at any address specified by the consumer.

Technical characteristics of fehrali

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 wire 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 wire is supplied in the 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 wire is available in regular quality (1) high quality (PC). The permissible deviation of electric resistance of 1 m wire from the nominal shall not exceed ± 5% for wire of higher quality, and ± 7% for wire of ordinary quality. In this variation of electrical resistance material within a coil (coil mandrels) must not exceed 4%.
