Corrosion Resistance:Superior resistance to seawater corrosion: Cu70Ni30 offers excellent resistance to corrosion in marine environments, especially seawater. The high nickel content enhances its ability to resist pitting, crevice corrosion, and biofouling, which makes it ideal for use in coastal and offshore industries.

Strength and Durability:With 30% nickel, Cu70Ni30 has higher strength compared to alloys with a lower nickel content (like Cu90Ni10), while still retaining good ductility. This allows the mesh to be used in more demanding applications, where high mechanical strength is required.

Good Workability: Cu70Ni30 alloy is ductile and can be easily woven or fabricated into mesh structures without significant loss of strength, making it versatile for various industrial and filtration uses.

Thermal and Electrical Conductivity:While copper is a good conductor of both heat and electricity, the higher nickel content in Cu70Ni30 reduces its conductivity slightly, but the alloy still maintains decent electrical and thermal conductivity.

Biological Fouling Resistance:This alloy is known for its anti-biofouling properties, which is crucial for marine environments where algae, barnacles, and other marine organisms can adhere to surfaces.

Marine Engineering and Offshore Applications:

• Seawater filtration systems: Used in water filtration systems to remove debris, sand, and other particles from seawater, especially in desalination plants.
• Marine hardware: Used for manufacturing marine filters, nets, and screens, as well as in heat exchangers for ships and offshore platforms.
• Corrosion-resistant structural mesh: This mesh is used for structural reinforcement in marine and offshore environments, such as on oil rigs and in ship hulls, where resistance to saltwater corrosion is crucial.

Heat Exchanger and Cooling Systems:

• Cu70Ni30 is ideal for heat exchangers and cooling systems, particularly in environments with high exposure to seawater or corrosive chemicals. Its high corrosion resistance makes it reliable for use in cooling towers, condensers, and similar equipment.

Chemical and Petrochemical Industries:

• Chemical processing: Used in baskets, sieves, filters, and screens in chemical processing plants, especially where exposure to aggressive substances is common.
• Corrosive environments: Cu70Ni30 is often used in applications where materials must withstand exposure to chemicals like acids, alkaline solutions, and solvents.

Filtration and Sieving:

• The alloy mesh is commonly used for industrial filtration applications, such as in the food and beverage, pharmaceutical, and textile industries, due to its resistance to corrosion, biofouling, and wear.

Aerospace and Automotive:

• In some high-performance aerospace or automotive applications, Cu70Ni30 mesh is used in areas where strength and resistance to environmental degradation (like high temperatures or corrosive atmospheres) are crucial.
