Copper Nickel tubes C70600

Copper-nickel (also known as cupronickel) alloys offer excellent corrosion resistance to seawater and good fabricability. The addition of nickel to copper improves strength and corrosion resistance while allowing the alloy to remain ductile, other elements can be added to copper-nickel to increase strength, corrosion resistance, hardening, weldability and castability. The nickel-copper alloy has been widely used for r marine applications. C70600 often known as 90-10 copper-nickel, is the alloy with 90% cobre y 10% níquel, has been widely used in the automotive, admiralty, shipping, offshore as well as power generation.
