Household Appliances Cr20Ni80 Nickel Alloy Wire With High Temperature Resistance
Product Description:
Cr20Ni80 nichrome alloy wire is a high-performance electric heating
alloy material composed of nickel and chromium, known for its at
least 77% nickel content and excellent electric heating conversion
efficiency. This alloy wire has a high melting point of 1400-1450 °
C and an electrical resistivity of 1.1-1.2 μ Ω m, ensuring
stability and efficient energy conversion in high-temperature
environments. Its tensile strength of 637MPA and hardness of
HV400-500 provide necessary mechanical support, while its thermal
conductivity of 15-20 W/mK allows for rapid heat transfer. In
addition, the elongation of alloy wire exceeds 20%, which can meet
the processing needs of different applications, whether it is in
the hard or soft state. The surface treatment includes brightness,
oxidation, and acid washing, which increases its corrosion
resistance and aesthetics.
Cr20Ni80 nickel chromium alloy wire is widely used in the field of
household appliances, including electric kettles, ovens, water
heaters, electric blankets, and induction cookers. These
applications benefit from the rapid heating effect brought by their
high electrical resistivity, excellent stability at high
temperatures, and good mechanical properties. Whether as a heating
element or a resistance material, Cr20Ni80 alloy wire can provide
reliable and long-lasting performance, making it an indispensable
choice for electric heating materials in modern household
appliances.
