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 industries that require durability and seawater resistance. They are commonly utilized in marine applications such as seawater piping, condenser tubes, heat exchangers, pumps, and valves. In shipbuilding and offshore platforms, they play a crucial role in seawater cooling systems, hull components, and marine hardware due to their resistance to biofouling. Power generation and desalination plants also rely on them for tubing systems and evaporators. Moreover, the chemical processing industry employs them in equipment that is exposed to harsh conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
