Al Summan Metals, based in Dubai, UAE, distinguishes itself as a leading manufacturer and supplier of premium **Copper Nickel 70/30 Forgings**. Known for their accuracy and toughness, Al Summan Metals follows international standards closely, creating forgings that deliver outstanding corrosion resistance together with impressive mechanical strength. The 70/30 copper-nickel alloy, made up of 70% copper and 30% nickel, is particularly valued for its notable capacity to withstand seawater corrosion, biofouling, and erosion, making it an ideal choice for marine and offshore applications. Owing to advanced forging methods and a dedication to strict quality control, Al Summan Metals’ Copper Nickel 70/30 Forgings ensure dependable, long-lasting performance across numerous critical industries.
These forgings, composed of 70% copper and 30% nickel, frequently contain small quantities of iron and manganese to enhance their strength and resistance to corrosion. This alloy is recognized for its outstanding toughness, ductility, and resistance to stress corrosion cracking, while still preserving good thermal and electrical conductivity. Mechanically, the forgings feature a tensile strength of roughly 400–600 MPa and high yield strength, making them ideal for high-pressure, high-stress, and demanding environmental conditions.

Copper Nickel 70/30 forgings achieve their durability through outstanding corrosion resistance, high tensile strength, excellent weldability, seawater resistance, anti-biofouling characteristics, and uniform alloy composition for improved performance.
Copper Nickel 70/30 forgings deliver greater strength, better resistance to corrosion, more efficient material use, less waste, a finer grain structure, and increased durability when compared to machining, which makes them well suited for challenging applications.
Suitable welding methods for Copper Nickel 70/30 forgings include TIG (GTAW), MIG (GMAW), and shielded metal arc welding (SMAW), delivering robust joints, superior corrosion resistance, and reduced thermal distortion.
Copper Nickel 70/30 Forgings are widely applied in marine and industrial environments where resistance to corrosion and dependable mechanical performance are essential. They work ideally for seawater piping systems, ship hulls, condensers, heat exchangers, valves, and fittings. In addition, they serve in offshore oil and gas platforms, desalination plants, and power generation equipment, delivering lasting performance even under severe conditions. Thanks to their exceptional combination of durability, corrosion resistance, and strength, Copper Nickel 70/30 Forgings are the preferred option for challenging engineering, marine, and industrial applications.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
