Product Description

New Constantan Foil/ Cu-Ni Alloy 6j11 Foil
Constantan 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.
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
Shanghai Tankii Alloy Material Co., Ltd. is the most professional producer of constantan, copper nickel alloys in wire, strip, foil, sheet and rod.
