C0.26x3.0mm CuNi40 Constantan flat wire CuNi44 Constantan Ribbon CuNi45 Alloy Wire

 

Copper nickel alloy, which has low electric resisitance, 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 Kanthal's type cupronickel .
