→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.
