Nichrome 80

General Description

Nichrome 80 (UNS N06003/2.4869) is a high grade austenitic alloy. Due to its ductibility and strength at high temperature, Nichrome 80 is especially suitable for applications in the electrical appliance industry. In industrial furnace use Nichrome 80 has many advantages due to its excellent mechanical properties in the hot state. Nichrome 80 has superior life compared to competitive FeCrAl alloys because of the extremely good adhesion properties of the surface oxide.

Typical applications for Nichrome 80 are ironing machines, water heaters, resistors, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements and so on.
