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.
These Copper Nickel 90/10 forgings find extensive use in marine and industrial sectors thanks to their remarkable corrosion resistance and mechanical strength. Typical applications include shipbuilding components like propeller shafts, pump parts, and seawater piping systems. They’re also found in heat exchangers, desalination plants, and chemical processing equipment. The alloy’s ability to resist biofouling and seawater erosion makes it a great choice for offshore platforms and underwater pipelines. Additionally, these forgings are utilized in the electrical and electronic industries, where their excellent conductivity and durability come in handy.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
