Founded in Kuala Lumpur, Malaysia, Aiman Metals is a reputable producer and supplier of high-quality metal products, providing precision-engineered solutions to markets all over the world. Of its specialties, the company specializes in Copper Nickel 90/10 Forgings, which are known for their strength, dependability, and excellent corrosion resistance. Engineered to withstand harsh conditions, these forgings are used in the marine, chemical processing, power generation, and desalination industries. Their high durability makes them extremely worthwhile in seawater systems and industrial machinery demanding stable performance. With intense focus on quality, precision, and customer satisfaction, Aiman Metals provides products that assure efficiency and long-term reliability for demanding applications.
Copper Nickel 90/10 Forgings consist of around 90% copper and 10% nickel with minor additions of iron (1–1.5%) and manganese (1–1.5%) that improve mechanical properties and corrosion resistance. These forgings have tensile strength of 310–480 MPa, yield strength of 110–280 MPa, and elongation of 30–50%, varying with the forging process. Brinell hardness is normally in the range of 90–180 HB. The alloy is also very weldable, conducts heat well, and is fatigue-resistant, in addition to superior seawater corrosion resistance and biofouling resistance, qualifying it for harsh and aggressive marine and industrial conditions.

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 broad applications in industries that require high strength, corrosion resistance, and durability as well as seawater corrosion resistance. In the shipbuilding industry, they find extensive applications in shipbuilding, pumpings, valves, fittings, heat exchangers, and sea water piping systems because of its superior biofouling resistance. In power generation and desalination processes, they are used in condenser tubes, cooling circuits, and structural components exposed to saltwater. The chemical processing industry employs them in tanks, pipelines, and processing equipment since they resist aggressive chemicals well. Due to good machinability and resistance to stress corrosion cracking, these forgings are very dependable for rigorous industrial service.
