Konstantan StripKonstantan 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.
Other grade of copper nickel alloy are as follows:
CN5, CuNi2
A60, Alloy 60, 60 Alloy, MWS-60, Lohm, HAI-60, CuNi 6, Alloy 260, Nickel Alloy 60, CN10
CuNi10, CN15
A30, Alloy 30, CuNi23, 30 Alloy, MWS-30, HAI-30, Alloy 230, Nickel Alloy 30, CN 30
CuNi1, CuNi15, CuNi30
