CuNi2 is a low-resistance copper nickel alloy containing approximately 2% nickel. It is formulated to provide a low and stable electrical resistivity together with an exceptionally low temperature coefficient of resistance (TCR), making it a cost effective choice for low temperature heating, precision resistance and compensating lead applications. The wire is supplied in a bright, soft annealed condition with excellent ductility for winding and coiling.
