Headquartered in Manila, Philippines, Isis Metals is a reliable producer and distributor of quality steel and alloy materials, with specialization in Copper Nickel 90/10 Forgings. Known for its accurate engineering and quest for excellence, Isis Metals provides industries including marine, chemical processing, and power generation with high-quality metal solutions. Made up of 90% copper and 10% nickel, our Copper Nickel 90/10 forgings are renowned for their exceptional corrosion resistance, strength, and durability, which make them suitable for harsh conditions and seawater systems. Isis Metals is committed to delivering products that provide high performance, reliability, and long service life in challenging applications.
Copper Nickel 90/10 Forgings have 90% copper and 10% nickel, with a small amount of iron (Fe) and manganese (Mn) added to improve strength and corrosion resistance. The alloy provides tensile strength of 310–480 MPa, yield strength of 160–280 MPa, elongation of 30–50%, and Brinell hardness of 90–180 HB. It has good resistance to seawater corrosion, biofouling, and stress corrosion cracking, and good thermal conductivity, weldability, and formability. These characteristics render Copper Nickel 90/10 forgings highly resistant and trustworthy for key applications in the marine, power generation, and chemical processing sectors.

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.
Copper Nickel 90/10 Forgings are popular throughout industries that require better corrosion resistance, strength, and durability. In the naval sector, they are critical in shipbuilding, seawater piping, pumps, valves, and heat exchangers, owing to their high resistance to biofouling and seawater corrosion. They also find application in power stations, desalination plants, and chemical works for parts like condensers, fittings, and heat exchangers. Featuring outstanding stress corrosion resistance, workability, and thermal conductivity, Isis Metals’ Copper Nickel 90/10 forgings ensure long-term performance in corrosive environments, providing safety, efficiency, and reliability in harsh engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
