A reputable company in Houston, Texas, Elvis Nickel Alloys is a top producer and supplier of Copper Nickel 70/30 Tube Fittings, which are renowned for their exceptional corrosion resistance and durability. These fittings, which are made of a high-strength 70/30 copper-nickel alloy (70 percent copper and 30 percent nickel), are perfect for harsh industrial, offshore, and marine settings. Our tube fittings are available in a range of sizes and configurations and are designed to provide reliable performance in high-pressure and high-temperature applications. They also meet international quality standards. For vital piping and fluid handling systems around the world, Elvis Nickel Alloys is committed to accuracy, quality control, and prompt delivery.
Copper Nickel 70/30 Tube Fittings are made up of 70% copper and 30% nickel, with trace amounts of manganese and iron added to improve their mechanical qualities and resistance to corrosion. With tensile strengths ranging from 350 to 550 MPa and exceptional elongation of up to 30%, these fittings guarantee flexibility and longevity. In high-velocity flow conditions, the 70/30 alloy offers exceptional resistance to erosion, stress corrosion cracking, and seawater corrosion. It is appropriate for demanding applications needing structural integrity under pressure and temperature fluctuations in extremely corrosive environments because it also retains good thermal and electrical conductivity.
