Commonly known as cupro-nickels, a range of copper nickel alloys exists that posseses varied properties and thus are used in different applications.
Some popular copper nickel alloys are-

• Copper with 30% nickel
• Copper with 10% nickel

All the copper nickel alloys for copper nickel alloy tubes have only one phase since the copper nickel binary system shows complete solid solubility.

• Generally properties vary in accordance to the composition, some properties are mentioned below The major variety are- Copper 90/10 and Copper 70/30
• The 70/30 variety is more stronger and exhibits superior resistance to impingement corrosion
• It exhibits outstanding resistance to corrosion in particular to sea water
• It offers good resistance to biofouling as 90/10 alloy being slightly superior compared to the 70/30 alloy

Alloys rich in copper exhibit the following features

• Good corrosion resistance
• Ductile
• good strength
• Can be hardened only by cold working
• Low temperature co-efficient of electrical resistance
• The nickel content helps the alloys to retain strength even at elevated temperatures as compared to copper alloys without nickel.

Such Cupro Nickel tubes & pipes for Marine application are very vital for all industrial fields. The company's vast experience in the related field enables them to supply such tubes in accordance to the international standards with specific customer requirements.

The 90/10 nickel alloy tubes are used as sea water condensor systems and desalination plants owing to good resistance against sea water corrosion and also for pipe work in chemical plants.

Due to the fact that 90/10 alloy requires no surface protection thus providing extra safety, they are extensively used in the automotive applications for brake and hydraulic suspension systems and also as cooling systems in commercial vehicles and cars.

90/10 Copper Alloys are also extensively used in marine applications owing to it's characteristic of good resistance to biofouling and sea water corrosion resistance and are used in applications such as cladding for ships' hulls, legs of oil rig platforms and sea water intake screens.

There are some other application areas of 90/10 copper alloy tubes like,
These tubes are used in

• Ammunition
• Sea water corrosion-resistant assemblies
• Condenser tubes
• Cooling circuits

The Copper nickel alloy of the ratio 90/10 has high erosion and corrosion resistance and high weld ability, is easy to install hence is used for condensors, ship building and refineries.
