0.01mm 0.02mm 0.03mm Nichrome Alloy 80/20 / MWS-650 Strip / Foil Used For High-Precision Resistors
The alloy 80/20 is mainly composed of elements such as nickel (Ni),
chromium (Cr), copper (Cu), manganese (Mn), etc., with nickel
content of about 80% and chromium content of about 20%. Its
resistivity is stable and changes very little in high and low
temperature environments, making it suitable for electronic devices
that work for a long time.
Nickel-chromium alloy with high and stable resistance, corrosion resistance, surface oxidation resistance, excellent coil- forming ability.it is an ideal material,it has good ductility,workability and weldability under high temperature and seismic strength.
