Copper Alloy No. C70600 is a very resistant alloy in a seawater service. Failure in properly designed systems in such environments by general corrosion, pitting, crevice attack and stress-cracking can be discounted for this copper nickel alloy. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-557. Producer or source: Copper and copper alloy mills.
