Product Description Recommend Constantan Wire CuNi44 Copper Nickel Alloy Wire Used in Industrial FurnacesConstantan is a copper-nickel alloy usually consisting of 55% Copper and 45% Nickel. Its main feature is its resistance which is constant over a wide range of temperatures. It is also called Alloy 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 44, CuNi 44, CN49.Chemical Content(%)MnNiCu1.044Bal.
