Types of resistance wire

‌The types of resistance wire mainly include the following:

‌Nickel-chromium alloy resistance wire‌: Commonly used in high-temperature heaters and resistors, with good oxidation resistance and corrosion resistance. Common alloys include Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr20Ni30 and Cr25Ni20, etc.
‌Fe-Cr-Aluminum alloy resistance wire‌: Suitable for environments requiring high temperature and strong corrosion. Common alloys include 0Cr25Al5, 0Cr21Al6, 0Cr21Al6Nb, 0Cr23AL5, 1Cr13AL4 and 1Cr21AL4, etc.
‌Fe-Aluminum alloy resistance wire‌: Mainly used in thermostats and thermistors, insensitive to environmental humidity and temperature changes.
These types of resistance wires are suitable for different application scenarios according to their materials and properties. For example, nickel-chromium alloy resistance wire is often used in high-temperature heaters due to its good oxidation resistance and corrosion resistance; while iron-chromium-aluminum alloy resistance wire is suitable for environments requiring high temperature and strong corrosion. Iron-aluminum alloy resistance wire is mainly used in thermostats and thermistors and is insensitive to environmental changes.
