====<!--5.1.5.2-->Copper-Nickel-Tin Alloys====
Copper-Nickel- multi component alloys with 9 wt% Ni and 2 wt% Sn are used mainly as connector materials because of their suitable mechanical properties, their excellent relaxation behavior, and their high corrosion resistance. Other advantages include their high temperature stability and the good solderability , even after longer storage. They are also used as base materials for clad profiles and tapes. <xr id="fig:Phase_diagram_of_copper-nickel_for_the_range_of_0-50_wt_nickel"/><!--Fig. 5.21:--> Phase diagram of copper-nickel for the range of 0 – 50 wt% nickel <xr id="fig:Electrical_conductivity_of_copper-nickel_alloys_as_a_function_of_nickel_content"/><!--Fig. 5.22:--> Electrical conductivity of copper-nickel alloys as a function of nickel content
