Ni35Cr20 alloy wire is a classic nickel-chromium resistance heating alloy material. It features high electrical resistivity, excellent high-temperature oxidation resistance, and stable thermal performance.
This wire owns good mechanical strength and corrosion resistance, able to work steadily under harsh high-temperature environments. Widely applied to industrial furnace heating elements, electric heating tubes, household heaters, drying ovens, automotive heating systems, precision resistors, and thermal treatment equipment. It serves as core heating and electric resistance parts for metallurgy, chemical, electronic, and mechanical manufacturing industries.
