Product Description

Resistance Constantan Wire CuNi40 /CuNi 44 Nickel copper flat wire

Copper nickel alloy,which has low electric resistance,good heat-resistant and corrosion-resistant, easy to be processed and lead welded.It is used to make the key components in the thermal overload relay,low resistance thermal circuit breaker, and the electrical appliances.It is also an important material for electrical heating cable.It's similar as s type cupronickel.
Appicaton:
Low-voltage circuit breaker, thermal overload relay, electrical heating cable, electrical heating mats, snow melting cable and mats, ceiling radiant heating mats, Floor heating mats & Cables, Freeze protection cables, electrical heat tracers, PTFE heating cables, hose heaters, and other low-voltage electrical product
