Sabra Metals, operating from the heart of Amman, Jordan, stands as a distinguished manufacturer and supplier of high-performance metal components. We take particular pride in our expertise with CuNi 90/10 forgings, a material perfectly suited for demanding environments. Our forging process enhances the alloy’s natural strengths, producing parts with exceptional reliability that are trusted by industries where failure is not an option, from marine engineering to critical chemical processing.
The composition of CuNi 90/10 is precisely defined, containing 90% copper and 10% nickel, with carefully controlled additions of iron and manganese. This specific blend gives the alloy its renowned mechanical properties. It offers excellent corrosion resistance, particularly against seawater, and maintains good strength and ductility across a wide range of temperatures. Furthermore, it is highly resistant to biofouling and stress corrosion cracking, making it an incredibly durable and long-lasting material choice.

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.
The uses for these forgings are extensive, primarily because of their exceptional performance in marine settings. You will find them in critical shipboard systems like seawater piping, pumps, and valves, as well as in offshore platforms and desalination plants. Beyond the sea, their corrosion resistance is invaluable in the chemical and petrochemical industries for processing equipment, and in power generation for condenser tubes and heat exchangers, handling corrosive fluids with steadfast reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
