Copper-nickel alloys wire mesh/screen (often referred to as cupro-nickels) offer moderate to high strength and excellent resistance to various waters, including seawater and form a protective surface film in such conditions. In addition they provide good anti-fouling properties and weldability.
The precipitation hardenable copper nickels (DEF STAN 02-835 and ULTIBRON™-NB) possess high strength and are used as an alternative to the 90/10 and 70/30 alloys and other copper alloys such as nickel aluminium bronze in marine applications. Other useful attributes include low magnetic permeability, imperviousness to hydrogen embrittlement, no loss of impact strength down to minus 196°C and good jet impingement resistance.
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:
1.Copper with 10% nickel
2.Copper with 30% nickel
3. Copper with 25% nickel with 0.05-0.4% manganese
4. 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.
Copper Nickel Alloy Wire Mesh/Screen Key Properties:
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. The nickel content in these alloys also enables them to retain their strength at elevated temperatures compared to copper alloys without nickel.Chemical Composition ( %)
