High resistance alloys are characterized by high resistivity, stable resistance-temperature coefficient, high temperature resistance and oxidation resistance. They are mainly divided into two categories:
1. Electric heating alloys (nickel-chromium, iron-chromium aluminum) - for power-on heating
2. Precision high-resistance alloys (nickel-chromium-aluminum, Karma alloy, etc.) - for precision resistor components
