Cr20ni80 Nickel Chrome Alloy Wire Micc Nickel Chrome Resistance Alloy Wire Cr20Ni80
NiCr Series
Nichrome wire is a non-magnetic alloy consisting mainly of nickel, chromium, and iron. It has high resistivity and good oxidation resistance, as well as good ductility and weldability. Due to these properties, nichrome wire and strips are commonly used to produce heating elements in electric furnaces, thermal devices, heat guns, industrial hair dryers, water heating systems, high-value electrical resistors, heating cords, and cables.
Size dimension range:
Wire: 0.01-10mm
Ribbons: 0.05*0.2-2.0*6.0mm
Strip: 0.05*5.0-5.0*250mm
NiCr series: Cr20Ni80, Cr30Ni70, Cr15Ni60, Cr20Ni35, Cr20Ni30
