Other Naturally Hard Copper Alloys

Copper-Nickel Alloys

Copper and nickel are in their solid and liquid phase completely soluble in each other . Because of their very low electrical conductivity they are mainly used as resistance alloys . The work hardening and softening behavior of CuNi alloys and CuNi9Sn2 are shown in (Figs. 3 – 7). Coppernickel alloys exhibit high corrosion resistance, good weldabilty, and the suitability for cladding to other materials. Because of the...
