Relevance
Nichrome wire Kh20H80 contains up to 78,8% Ni, 19-20% Cr, also includes up to 1% Si and up to 0.7% Mn, the rest is Iron. Nichrome Cr20Ni80 is alloyed with rare-earth metals such as zirconium to improve the physico-chemical properties, to achieve a longer lasting stable operation.

Nichrome filament up to 2 mm thick is usually used for heating elements of electric thermal equipment of increased reliability as a heat-resistant and chemically resistant alloy for non-resistive resistors that can work in aggressive environments. Due to its properties, it has a high operating temperature up to about 1100 °C, mechanical strength. In addition - it is a mandatory requirement for such materials - high resistivity.
Selection
Nichrome wire is an indispensable element of heating parts of vacuum devices and connectors of electronic equipment. It is subject to the general rule of diameter selection to operate at 220 volts. It is necessary to choose a wire whose allowable current strength is not less than the design current through the heater.
Calculation
Using a simple arithmetic ratio, it is not difficult to calculate the length of nichrome wire for a different voltage. Let's say we need to determine the length of filament for winding on a rod of 3 mm. The recommended length of such filament for 380 volts would be 16 cm. Make the proportion: 380 volts - 16 cm, and 220 volts - X cm
Then: X=220 multiplied by 16 and divided by 380, we get 9 cm.
After winding a 9 cm length of X20H80 nichrome filament on a rod, without cutting it, connect it to the voltage to make sure it is winded correctly.
Labeling
The marking of nichrome wire reflects the percentage composition of the elements In this case - X20H80 is 20% chromium and 80% nickel. By default, the alloy is introduced additional components such as: silicon, manganese, aluminum.
