High-Temperature Resistance Of Cr10Ni90 Nichrome Alloy Wire For Industrial Furnaces And Heaters

Introduction:

Cr10Ni90 nickel-chromium alloy wire is a high-performance resistance heating material, mainly composed of 90% nickel and 10% chromium, with excellent high-temperature strength, oxidation resistance and corrosion resistance. The maximum operating temperature of this alloy wire can reach 1300℃, the melting point is about 1400℃, the density is 8.7 g/cm³, and the resistivity is 1.09±0.05 μΩ·m at 20℃. Its good ductility and welding properties make it easy to process into heating elements of different shapes. Cr10Ni90 alloy wire is widely used in industrial furnaces, heaters and other high-temperature equipment, especially suitable for use in high temperature and corrosive environments.

Applications:

1. Electric heating elements: widely used in the manufacture of electric heating wires, electric heating rods, etc., and applied to heating equipment such as electric kettles, ovens, and industrial furnaces.
2. Industrial heating equipment: used for high-temperature heaters, heat treatment equipment, etc. in the chemical and petroleum industries.
3. Resistor elements in corrosion-resistant environments: suitable for heating equipment under complex conditions such as seawater and acidic environments.
4. Electronic and electrical fields: used to manufacture components such as resistors and potentiometers.
5. Thermocouple materials: can be used for temperature measurement and control equipment.
