Nestled in the heart of Manama’s bustling industrial landscape, Junaid Metals has built a reputation for excellence, particularly with their expertly crafted Copper Nickel 9010 forgings. We understand that components for demanding marine and industrial environments require unwavering reliability. That’s why our forgings are produced with meticulous attention to detail, ensuring they deliver superior performance and longevity, giving our clients the confidence to tackle their most challenging projects with a trusted local partner right here in Bahrain.
The strength of this alloy comes from its composition, primarily 90% copper and 10% nickel, with small additions of iron and manganese for enhanced performance. This blend results in forgings with exceptional mechanical properties, including high tensile strength and excellent ductility. They are particularly valued for their outstanding resistance to corrosion, especially in seawater, and their ability to withstand biofouling, making them a structurally sound and durable choice for critical 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.
You’ll most often find our 90/10 Copper Nickel forgings hard at work in the marine industry, forming essential parts like seawater pump shafts, propeller systems, and submarine fittings. Their reliability also makes them ideal for critical components in offshore oil and gas platforms, as well as within desalination plants and power generation facilities where cooling systems use seawater. Essentially, wherever equipment faces the relentless challenge of saltwater corrosion, our forgings provide a robust and long-lasting solution.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
