CuNi 70/30 ASTM B466 Seamless Tubing 3-1/2" OD x 0.095" Wall Thickness

Properties of copper nickel alloys vary with composition, however, some properties of copper nickel alloys are outlined below.

Copper-Nickel alloy Copper 90/10 and Copper 70/30

  • Outstanding resistance to corrosion, particularly sea water
  • 70/30 is stronger and has superior resistance to impingement corrosion
  • Good resistance to biofouling, with the 90/10 alloy being slightly superior compared to the 70/30 alloy

Copper rich alloys are:

  • Ductile
  • Can be hardened only by cold working
  • Good corrosion resistance
  • Good strength
  • Low temperature co-efficient of electrical resistance

The nickel content in these copper nickel alloys also enables them to retain their strength at elevated temperatures compared to copper alloys without nickel.

Applications of Copper Nickel alloys

Sea Water Condensor Systems And Desalination Plants

Due to the good resistance to sea water corrosion, the copper nickel alloy Copper 90/10 and copper nickel alloy Copper 70/30 are employed for sea water condenser systems and in desalination plants, as well as pipe work in chemical plants.

Automotive Applications

Due to the fact that the copper nickel alloy Copper 90/10 requires no surface protection and hence gives extra safety, this copper nickel alloy is being increasingly employed for brake and hydraulic suspension systems and cooling systems in cars and commercial vehicles.

Marine Applications

The good resistance to biofouling and sea water corrosion resistance of the copper nickel alloys, Copper 90/10 and Copper 70/30 alloys have lead to its use in applications such as cladding for ships' hulls, legs of oil rig platforms and sea water intake screens.

Coins

The copper nickel alloys composed of copper with 25% nickel with 0.05-0.4% manganese is commonly used for the manufacture of coins, medals and other semi valuable applications.

Resistance Wire

Due to the very low temperature co-efficient of electrical resistivity, the copper nickel alloys composed of copper with 45% nickel alloy is used for resistance wire in high precision resistors. This property of copper nickel alloys allows the resistor to operate at almost exactly the same resistance regardless of temperature.

Thermocouples

The copper nickel alloys composed of copper-45% nickel alloy is also used for thermocouples as it develops a high and uniform EMF when coupled with other metals such as copper and iron.

Other Applications

Copper nickel alloys are also used in cooling circuits, ammunition, sea water corrosion-resistant assemblies, condenser tubes.
