Based in Houston, Texas, George Metals is a reputable manufacturer and supplier of Copper Nickel 70/30 Nuts, catering to various industries. Premium 70/30 copper-nickel alloy is used in the engineering of our nuts to provide exceptional corrosion resistance, particularly in environments with harsh chemicals and saltwater. These nuts, which are made for high-performance applications, provide exceptional mechanical strength, resilience, and dependability under harsh circumstances. To satisfy global standards, George Metals manufactures Copper Nickel 70/30 Nuts in a variety of sizes and dimensions. We are a trustworthy partner for essential fastening solutions globally, with an emphasis on quality, consistency, and customer satisfaction.
About 70% copper and 30% nickel make up Copper Nickel 70/30 Nuts, with trace amounts of iron and manganese added for strength and corrosion resistance. When exposed to high temperatures and salinities, this alloy performs exceptionally well. Mechanical characteristics include good ductility with elongation up to 30% and a tensile strength of approximately 380–550 MPa. These nuts are perfect for demanding marine and industrial applications where mechanical integrity and long service life are crucial because of their remarkable resistance to stress corrosion, cracking, erosion, and biofouling.
