Hemi Metals is a trusted manufacturer and supplier based right here in Hamilton, New Zealand, specializing in high-performance materials. We take particular pride in our expertise with Copper Nickel 9010 forgings, a material prized for its exceptional durability and resistance to harsh environments. Our team is dedicated to producing robust, precision-engineered components that meet the most demanding specifications, ensuring our clients receive reliable solutions that stand the test of time for critical industrial and marine applications.
The unique composition of Copper Nickel 90/10, with its 90% copper and 10% nickel blend, along with small additions of iron and manganese, is what gives it such remarkable strength. This alloy offers outstanding mechanical properties, including high tensile strength and excellent ductility. It maintains these properties across a wide range of temperatures and is highly resistant to corrosion, especially in seawater, making it an incredibly tough and reliable material for forged components that must perform under pressure.

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, particularly in industries where failure is not an option. You’ll find them in critical marine systems like shipbuilding, offshore platforms, and desalination plants, where their resistance to saltwater corrosion is invaluable. They are also essential in the power generation and oil and gas sectors for components like valves, pumps, and fittings. Essentially, wherever components face aggressive, corrosive environments, Copper Nickel 9010 forgings provide a trusted, long-lasting solution that minimizes maintenance and maximizes operational uptime.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
