Elvis Nickel Alloys is a top producer and supplier of premium-grade Copper Nickel 90/10 Flanges designed for long-term durability and corrosion resistance in industrial and marine piping systems. The company is based in Houston, USA. Our flanges, which are made of a dependable alloy consisting of 90% copper and 10% nickel, are made to perform at their best in harsh chemical and seawater environments. To satisfy a variety of application requirements, we provide an extensive selection of flange types, including socket weld, slip-on, blind, and weld neck. Elvis Nickel Alloys guarantees excellent flange solutions for important infrastructure projects with precise machining, stringent quality standards, and timely delivery.
90% copper and 10% nickel make up Copper Nickel 90/10 Flanges, with trace amounts of iron and manganese added for strength and corrosion resistance. These flanges usually have a tensile strength between 310 and 450 MPa and are highly ductile, elongating up to 30%. Particularly in environments with seawater and brine, they continue to exhibit exceptional resistance to stress corrosion, cracking, erosion, and biofouling. Strong, leak-proof connections in piping systems are ensured by the alloy’s stable mechanical and thermal characteristics, which make it perfect for use in high-moisture and moderately high-pressure environments.
