Annealed Soft Surface Nicr Alloy Round Wire Nicr80 / 20 Diameter 0.061 0.071mm
Ni80Cr20 (Nichrome) alloy is a brand name for a nickel-chromium resistance wire, a non-magnetic alloy of nickel and chromium.
A common alloy is 80% nickel and 20% chromium, but there are many others to accommodate various applications.
It is silvery-grey in colour, is corrosion resistant, and has a high melting point of about 1400 °
Ni80Cr20 is 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.
