C71500 copper-nickel, also known as 70/30 copper-nickel, offers good corrosion resistance, especially in marine saltwater environments. The primary forged copper-nickel alloys selected for use in seawater service contain 10% or 30% nickel. They also have the important additions of iron and manganese, which are necessary to maintain good corrosion resistance. It retains its strength well at moderate temperatures, has good cold and hot workability, and is easy to weld. This alloy is now used in a wide range of applications, from pipes for seawater and cladding for offshore platforms to underwater cages for fish farming. Some common applications for copper nickel include valves, pump assemblies, fittings, flanges, and various other marine hardware components.
Copper Nickel UNS C71500 fittings have a large safety factor, making them suitable for heat exchangers and condensers. We offer a wide range of cupronickel forged fittings such as cupronickel tees, cupronickel 90-10 couplings, cupronickel 70/30 unions, cupronickel forged elbows, bushings, plugs, etc.
Copper-nickel forged fittings are prominent in heavy engineering because of the following characteristics: resistance to corrosion, wear, stress rupture at high temperatures, pitting, and crevice cracking. These forged fittings can hold deformation and expansion at high temperatures. Forged fittings are ideally suited for use in chemical plant equipment to convey chemical media.
Copper-nickel fittings are widely used in piping systems and industries for redirecting the flow of liquids or reducing the size of pipes.
