Luois Metals is a reputable manufacturer and supplier of Copper Nickel 90/10 Forgings based in Houston, USA. We pride ourselves on delivering high-performance forgings that are built for strength, durability, and exceptional corrosion resistance. Crafted with precision and in line with international standards, our Copper Nickel 90/10 Forgings are highly regarded for their reliability in both marine and industrial settings. These forgings excel in resisting seawater, biofouling, and stress corrosion, making them the go-to choice for demanding applications. At Luois Metals, we are committed to maintaining consistent quality, timely delivery, and ensuring customer satisfaction with our Copper Nickel 90/10 Forgings across various industries.
Copper Nickel 90/10 Forgings consist of about 90% copper and 10% nickel, with small amounts of iron and manganese added to boost mechanical strength and corrosion resistance. This unique composition grants them excellent toughness, ductility, and resistance to erosion in both seawater and chemical environments. Mechanically, they provide good tensile strength, moderate hardness, and outstanding fatigue resistance, ensuring reliable performance even in high-pressure and corrosive conditions. The blend of strength and corrosion resistance makes these forgings ideal for critical industrial applications.
