Product Description
1.The picture of Nickel Chromium Ni80Cr20 electric resistance wire
Nickel Chromium Ni80Cr20 electric resistance wire is characterized by high resistivity, stable mechanical properties. Nichrome alloys have higher elongation, better ductility and weldability.
Nickel Chromium Ni80Cr20 electric resistance wire is widely used for making electric heating elements in home appliances and industrial furnaces. Typical applications are flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
