Headquartered in Kuala Lumpur, Malaysia, Aiman Metals is a reputed producer and supplier of high-quality metal products with a variety of solutions for various industrial requirements. With its quality, reliability, and innovation-based reputation, the company produces Copper Nickel Square Bars that make up for strength, durability, and exceptional corrosion resistance. Precisely engineered, these square bars are extensively utilized for uniform performance in marine, chemical, and aerospace industries. Through the supply of materials that can endure extreme conditions, Aiman Metals is committed to customer satisfaction and ongoing fulfillment of the increasing global need for high-quality, reliable metal products.
The Copper Nickel Square Bars are usually made up of 90/10 (90% copper, 10% nickel) and 70/30 (70% copper, 30% nickel) compositions. The 90/10 alloy enjoys superior resistance to seawater corrosion and low biofouling, making it suitable for marine use, while the 70/30 variant possesses greater tensile strength and better SCC resistance. The bars show tensile strength ranging from 300–550 MPa, hardness of 150–200 HB, and elongation up to 40%. With satisfactory machinability, thermal conductivity, and toughness, they provide consistent performance in harsh environments.

Yes, Copper Nickel Square Bars are customizable. They can be tailored in terms of size, shape, length, and specific alloy composition to meet the precise requirements of various industrial applications.
Copper Nickel Square Bars are used extensively in industries where corrosion resistance, strength, and durability are essential. In the marine sector, they are used in seawater systems, ship repair, desalination plants, and heat exchangers because they resist biofouling and seawater corrosion. In the petrochemical and chemical industries, they are used in valves, pumps, fittings, and process equipment. Aerospace and automotive companies are dependent on them for components where strength and thermal conductivity are both needed. Their electrical and thermal characteristics also qualify them for connectors, bus bars, and other electronic parts, providing consistent performance under extreme operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
