Sahil Metals is a trusted producer and distributor in Riyadh, Saudi Arabia, providing top-quality metal products designed for demanding industrial use. One of its specialty products is copper nickel 90/10 forgings, which are highly valued for their superior corrosion resistance, strength, and durability in extreme conditions. Supplying markets like marine, offshore, desalination, and chemical processing, Sahil Metals guarantees the highest quality forgings to international standards. It prides itself on precision manufacturing, prompt delivery, and guaranteed product reliability, making it a dependable ally for copper nickel alloy needs.
Copper nickel 90/10 forgings are made up of about 90% copper and 10% nickel with traces of iron and manganese added for increased mechanical toughness and resistance to corrosion. It is a good corrosion and stress corrosion cracking resistant alloy with biofouling resistance. Its mechanical properties include tensile strength between 200 and 400 MPa, weldability, and good ductility. The forgings are stable in marine and chemical environments and deliver longevity and reliable performance for being continuously exposed to saltwater and attacking chemicals.

Copper Nickel 90/10 forgings may face challenges like higher cost, susceptibility to galvanic corrosion in specific environments, and limited availability in some sizes, requiring precise processing and material sourcing.
Common welding processes compatible with Copper Nickel 90/10 forgings include TIG (GTAW), MIG (GMAW), and SMAW. Proper filler materials, such as CuNi rods, ensure strong, corrosion-resistant welds for optimal performance.
Durability of Copper Nickel 90/10 forgings is ensured by factors like corrosion resistance, proper heat treatment, precise manufacturing, adequate welding techniques, and protection against galvanic corrosion in marine and industrial environments.
Copper nickel 90/10 forgings find extensive use in severe-duty applications like pump components, valve bodies, flanges, fittings, and seawater piping systems. Due to their excellent resistance to corrosion by saltwater and biofouling, they are suitable for shipbuilding, offshore oil and gas platforms, and desalination plants. Copper nickel 90/10 forgings deliver structural integrity and corrosion protection required for long-term service in marine and chemical processing situations. Engineers depend on copper nickel 90/10 forgings for strength, resistance to degradation, and ability to survive severe service conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
