C71500 Copper Nickel Size & Price PDF

A copper-nickel alloy with 30% nickel content (C71500) typically exhibits the best resistance to impact corrosion and is resistant to most acids and water. It is suitable for highly corrosive environments, where it offers a longer service life than other copper alloys. C71500 is a corrosion-resistant alloy suitable for marine climates. It is commonly used in the manufacture of pipes.
