Introduction:
Nichrome wire, such as Ni80Cr20 wire, finds applications in various industries and products due to its unique properties. Some common applications of Nichrome wire include:
Heating Elements: Nichrome wire is widely used in heating elements for electric ovens, toasters, space heaters, industrial furnaces, and other heating appliances due to its high electrical resistance and ability to generate heat efficiently.
Resistors: It is used in resistors for regulating electrical current and voltage in electronic circuits.
Industrial Furnaces: Nichrome wire is used in industrial furnaces for high-temperature applications due to its excellent oxidation resistance and durability at elevated temperatures.
2. High temperature performance: Cr20Ni80 alloy wire can work stably in high temperature environments. It has a high melting point and good oxidation resistance, and can withstand high temperature environments in high temperature heating and heating element applications, with a maximum use temperature of up to 1200 degrees Celsius.
3. Resistivity: Cr20Ni80 alloy wire has moderate resistivity, making it a commonly used resistance wire material. Its resistivity is usually in the range of 1.09-1.12 μΩ·m and can be adjusted as needed.
4. Corrosion resistance: Cr20Ni80 alloy wire shows good corrosion resistance in common acid and alkali media. It can resist corrosion by acids and alkalis of general concentrations, but it still needs to be used with caution in special corrosive media.
