General Description

Nichrome 80/20 is a high grade austenitic alloy. Due to its ductibility and strength at high temperature, Nichrome 80/20 is especially suitable for applications in the electrical appliance industry. In industrial furnace use Nichrome 80/20 has many advantages due to its excellent mechanical properties in the hot state. Nichrome 80/20 has superior life compared to competitive NiCr alloys because of the extremely good adhesion properties of the surface oxide.

Typical applications for Nichrome 80/20 are ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements and so on.
