Starc Metals, a reputable manufacturer and supplier located in Canberra, Australia, has built a solid reputation for providing top-notch Copper Nickel 90/10 Forgings that meet international quality standards. These forgings are made up of 90% copper and 10% nickel, which gives them outstanding resistance to corrosion, particularly in marine and offshore settings. With cutting-edge forging techniques and precision engineering, Starc Metals ensures that their products boast superior dimensional accuracy, strength, and reliability. Their Copper Nickel 90/10 Forgings are highly sought after in various industries, including marine, chemical processing, desalination, and power generation, thanks to their durability and long-lasting performance.
Copper Nickel 90/10 Forgings are primarily composed of around 90% copper and 10% nickel, with small amounts of iron and manganese added to boost strength and corrosion resistance. This alloy is particularly effective at protecting against seawater corrosion, biofouling, and stress cracking. It also offers good thermal conductivity, ductility, and toughness, even under challenging operating conditions. With a tensile strength ranging from about 275 to 400 MPa and excellent weldability, Copper Nickel 90/10 Forgings are perfect for components that demand strength, stability, and superior corrosion resistance in both marine and 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 forgings are widely utilized in sectors where seawater resistance and high durability are crucial. They’re commonly found in shipbuilding, desalination facilities, and offshore oil and gas operations, where they are used to manufacture flanges, fittings, valve bodies, and pump components. In the power generation and chemical industries, they serve as condenser tubes, heat exchangers, and piping systems. Thanks to their remarkable resistance to erosion, biofouling, and high-pressure environments, Copper Nickel 90/10 Forgings are a dependable choice for demanding engineering and marine applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
