Their deep knowledge of metallurgy, combined with a dedication to customer satisfaction, has made Mourad Metals a go-to partner for clients looking for durable and corrosion-resistant Copper Nickel 90/10 forgings, both locally and globally.
Copper Nickel 90/10 forgings are made up of about 90% copper and 10% nickel, often with trace amounts of iron and manganese to boost strength and resistance to corrosion. This alloy showcases impressive mechanical properties, such as high tensile strength, good ductility, and resistance to stress corrosion cracking. It also performs remarkably well in seawater and other harsh environments, maintaining its toughness and stability across a wide temperature range. The unique combination of copper’s thermal conductivity and nickel’s strength makes these forgings perfect for demanding industrial applications.

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 are particularly popular in marine and offshore industries because of their outstanding resistance to seawater corrosion. You’ll often find them in pump shafts, valves, flanges, and heat exchanger components, where durability is essential due to constant exposure to salty environments. They’re also used in chemical processing, desalination plants, and shipbuilding, delivering reliable performance under high-pressure and high-temperature conditions. Thanks to their excellent fabrication properties and long service life, this alloy is a smart, cost-effective choice for engineers and designers who need materials that offer strength, corrosion resistance, and easy maintenance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
