Headquartered in Kuala Lumpur, Malaysia, Aiman Metals is a world-leading manufacturer and supplier of premium quality steel and alloy products to diverse industries across the globe. Aiman Metals excels in Copper Nickel 70/30 Forgings, which are known for their high durability, precision, and superior corrosion resistance. With established excellence in marine, oil & gas, power generation, and chemical processing industries, Aiman Metals always supplies products specifically designed to endure the toughest conditions. Copper Nickel 70/30 forgings are engineered to outperform in seawater piping, shipbuilding, and heat exchanger applications with long-term reliability and efficiency through superior engineering and consistent quality standards.
Copper Nickel 70/30 Forgings consist of about 70% copper and 30% nickel with minor additions of iron (0.4–1.0%) and manganese (0.4–1.0%) to provide corrosion resistance and strength. These forgings have tensile strength 310–483 MPa, yield strength 110–276 MPa, and elongation 20–40% based on the forging process. With a hardness level of 80–150 HB, the alloy has superior toughness, ductility, and erosion resistance. Above all, Copper Nickel 70/30 has superior seawater corrosion resistance and biofouling resistance, which makes it extremely useful in severe marine and industrial applications.

The durability of Copper Nickel 70/30 forgings is ensured by excellent corrosion resistance, high tensile strength, superior weldability, resistance to seawater, anti-biofouling properties, and consistent alloy composition for enhanced performance.
Copper Nickel 70/30 forgings offer superior strength, enhanced corrosion resistance, improved material utilization, reduced waste, better grain structure, and higher durability compared to machining, making them ideal for demanding applications.
Compatible welding processes for Copper Nickel 70/30 forgings include TIG (GTAW), MIG (GMAW), and shielded metal arc welding (SMAW), ensuring strong joints, excellent corrosion resistance, and minimal thermal distortion.
Copper Nickel 70/30 Forgings are highly employed throughout marine, chemical, and industrial applications where seawater corrosion resistance and high strength are critical. They find applications in shipbuilding in propellers, seawater piping, valves, pumps, and heat exchanger parts. Hydraulic tubing, structural parts, and items exposed to saltwater in offshore oil and gas platforms employ them. In power generation and desalination facilities, they are utilized in condenser plates, tubing systems, and cooling circuits. The biofouling resistance, erosion resistance, and high pressure resistance of the alloy also make it suitable for chemical processing equipment, providing durability as well as thermal efficiency for extreme operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
