Application

NiCr 8020 (2.4869) is used for 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.

• electrical parts and electronic components.
• electric heating elements (home & industrial use).
• industrial furnaces up to 1200 °C.
• heating cables, mats and cords.

Due to extremely good adhesion properties of the surface oxide, NiCr 80 20 offers superior service life compared to competitive nickel-chromium alloys.
