Product Description

Premium Heating Resistance Wire Copper-Nickel Cupronickel Alloys
 
OhmAlloy 005(Resistance heating wire and resistance wire)
Common Name: (CuNi2,NC5)

OhmAlloy 005 is a copper-nickel alloy (Cu98Ni2 alloy) with low resistivity for use at temperatures up to 200°C.

Cuprothal 5 is typically used for low-temperature applications such as heating cables in electric blankets and pillows.
