Copper Nickel Alloys
Sometimes called cupro-nickels, there exists a range of different copper nickel alloys that possess different properties and hence are suited to a range of different applications. Some of the better known copper nickel alloys include:
· Copper with 10% nickel
· Copper with 30% nickel
· Copper with 25% nickel with 0.05-0.4% manganese
· Copper with 45% nickel (also known as constantan)
All copper nickel alloys consist of only one phase as the copper nickel binary system exhibits complete solid solubility.
Advantages:
Very good resistance to corrosion
Very good malleability
Very good solderability
