General Description

NiCr 3020, also called Nikrothal 30, is used as electric components in domestic appliances and other electric heating equipments. It has good ductility after long time usage, good mechanical property at high temperature and good weldability. NiCr 3020 can be used at operating temperature up to 1000°C.

Typical applications for the NiCr 3020 is night-storage heaters, convection heaters and fan heaters. NiCr 3020 is also used in heating cables and rope heaters in defrosting and de-icing elements, electric blankets and pads, car seats, baseboard heaters, floor heaters, resistors, etc.
