DIN 86090 CuNiFe 90-10 Elbow C70600 For Shipbuilding, Marine Engineering And Seawater Pipeline Systems

DIN 86090 CuNiFe 90-10 Elbow is specifically designed for shipbuilding, marine engineering, and seawater piping systems.

CuNi 90/10 is a recognized material of choice for marine engineering. In seawater, it forms a dense, stable protective oxide film, effectively resisting uniform corrosion, pitting corrosion, and crevice corrosion.

Therefore, shipbuilding and repair are the core and most widely used areas for this product. Many critical internal piping systems extensively utilize 90/10 copper-nickel alloy elbows.
